difference between nonionic and cationic?
457736
Cationic means that a positive ion is formed, such that you have a charged ionic solution, such as salt water.  Nonionic means that you have a solution which presumably contains a detergent of some kind, like soap, but does not form an ionic solution.  Nonionic mixtures may enter hair more easily because of the lipid solubility.

NaCl IS A MOLECULE CALLED TABLE SALT!\nNH3 is not a molecule because the nitrogen atom is not bonded to another atom/atoms using all of its valence electrons and is therefore not a molecule, it is an ion.

cations form when the atoms lose an electron or more and have + valency , so the mass will decrease and the effect of the nuclei on the remaining electrons will be stronger so it attracts them stronger toward the center so the size will decrease .. while in the anions the number of electrons increase so the attraction caused by the nuclei is weaker so the size is larger ..\n\nsize of the cation of an element < size of the atom of that element < size of the anion of that element

If you mean conductometric TITRATION, it won't work.  Assuming they're both at the same concentration, you'll get a flat line.  Conductance is a rough measure of the ion concetration.  The start (H+ + Cl-) has the same number as equivalence (Na+ + Cl-).  Adding more (Na+ + OH-) past equivalence will not change the concentration either.

You cannot have one without the other.  If there are cations present, there will be an equally charged pile of anions there with it.  The charge on any system is always neutral (or very close - it may have some electrical potential but relatively speaking, it's very low).

None. They are two different compounds.\n\nIt looks like you want to compare a specific property of the alcohols. Please specify!

Na+ has a greater charge density than K+.  Both ions have the same charge, but Na+ is a smaller ion than K+.\n\nAl3+ has the greater charge density because of it's much higher charge.  (For that matter, it's also a much smaller ion than Na+.)\n\nAs far as a formula goes, the charge density would be the charge divided by the "volume" of the ion.  For practical purposes, it works to think of it as charge divided by radius as you suggest.  Increasing the charge or decreasing the size of the ion increases the charge density.

Ionic compound\n\n The crystal structure of NaCl, a typical ionic compoundIn chemistry, an ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. The positively charged ion is usually a metal ion and the negatively charged ion is non-metallic element or molecule.\n\nIons can be single atoms, as in common table salt sodium chloride, or more complex groups such as calcium carbonate. But to be considered ions, they must carry a positive or negative charge.\n\nThus, in an ionic bond, one 'bonder' must have a positive charge and the other a negative one. By sticking to each other, they resolve, or partially resolve, their separate charge imbalances. Positive to positive and negative to negative ionic bonds do not occur. (For a real world analogy, experiment with a pair of bar magnets.)\n\nIonic compounds have strong bonds between particles and thus generally have high melting and boiling points. They have good electrical conductivity when molten or in aqueous solution. While ionic inorganic compounds are solids at room temperature and will usually form crystals, organic ionic liquids are increasingly of interest.\n\nIonic compounds also dissolve in polarised liquids, of which water is an example, while they do not dissolve in organic liquids, such as Petrol. This is the opposite of covalent compounds.\n\nWhen an ionic compound is named, the cation is named first and then the anion. When an elemental anion is named, the suffix, -ide, is added to the name of the element. There are two common types of cations: Type I and Type II. Type I cations have only one charge and their name is simply listed when the compound is named. Type II cations have more than one charge and when the ionic compound is named, a Roman numeral is used to denote the charge of the cation. In addition, there are common polyatomic anions which do not have suffixes in their name such as hypochlorite (ClO–).\n\nRetrieved from "http://en.wikipedia.org/wiki/Ionic_compound"

A metal (Na) reacting with a non-metal (O) will produce a ionic bond, covalent bonds are usually only formed between two non- gases

NaOH is ionic.\n\nAll has to do with electronegativity and the difference between the two species bonded to each other.  If the electronegativity difference is less than 0.5, the bond is considered to be fairly non-polar.  Between 0.5 and 1.5 is usually a polar bond, greater than 1.5 usually means that there will be charge separation and the bond will be ionic.\n\nFor either polar or non-polar bonds, you need to know the geometry of the molecule and determine whether the sum of the individual dipoles in the molecule will cancel (vector sum).  If they do, the molecule is non-polar.  If they don't, it is.  For instance, water is polar as its polar bonds do not cancel geometrically, but CH4 is non-polar, even though each of its bonds is polar.

phosphate\nsulfate\nnitrate\nperchlorate\n\nThe oxidation state of the anion will not change.  These anions simply have a proton (or a couple protons) as the cation instead of a salt.  The name of the acid directly reflects the anion's name.  All the acids you listed had an -ic suffix which implies a fully oxidized state.  The per- prefix on perchloric sugggest it is one step beyond fully oxidized.  \n\nFor example, another oxoacid is sulfurous acid.  The -ous suffix informs us that the oxidation state of the non-oxygen element is lower than those with an -ic ending

They usually are not defined that way, but you can have:\n\n1. Redox in base solutions\n2. Redox in acid solutions\n3. Single species where the same species (such as I2) is bothe the oxidizing and reducing agent.\n4. Non water based\n5. Molten (no solvent at all) other than the components\n6.spontaneous/non-spontaneous

Ionic bonds are comprised of a metal and a non-metal.\nCovalent bonds are comprised of two bonded non-metals.

In covalent, atoms share electrons, but in ionic, one atom gives them to the other.  So in an ionic compound, there is a positive ion and a negative ion.  They ions can separate when put in water, and then the electricity can pass through.  Covalent compounds don't have a positive pole and a negative pole, and they don't ionize in water.  Also, the ionic bond is kinda stronger, so usually the compound is solid at room temperature (salt is ionic, oil is covalent).  You have to know that there is a third category, a polar molecule (like water).

Atoms do not have a charge.\nIons have a charge (either plus or minus)

Since the reaction is between two ionic compounds, it will be double replacement.  In that case, the positive ion of one compound switches places with the positive ion from the other.  The two products will then be sodium chloride (NaCl) and Calcium Carbonate (CaCO3).  Sodium Chloride is soluble, as are all ionic compounds with group 1 ions present, however, carbonate compounds are almost never soluble in water.  The only water-soluble carbonate compoounds that I can think of are ammonium carbonate and group 1 carbonate compounds.

Okay, take notes:\n\nORGANIC = anything with CARBON (except for inorganic carbon such as carbonate anion)\n\nINORGANIC = anything else
