NaCl? (sodium-chloride)?

Being the eraser is rubber (or something similar), it tends to not interact with polar materials (water, ionic materials like salt, and the like). Because of this, salt crystals rarely get a place to start growing on the eraser. The string is likely made of cotten or cotten containing, which has polar elements where the salt could adhere and start growing.\n\nThe bottom of the container doesn't need to have anything adhere to it, gravity keeps the salt which has crystalized and not sticking to something, at the bottom.

The formula for table salt is NaCl (Sodium Chloride). It exists in face-centred crystal lattices.

Depends on your salt substitute, but the answer you're looking for is probably Cl- as your salt substitute probably contains KCl.

If you mean NaCl (letter L at the end instead of number one), then, yes, sodium chloride is an ionic compound. In solid form it is NaCl(s), commonly known as table salt.\n\nIn case you're wondering, the formula NaCl is actually considered a "formula unit" rather than a "molecule." In solid form, ionic compounds are 3-D matrices of ions. But when dissolved or solvated in water, the ions become free floating Na+ and Cl- ions rather than individual NaCl units. A formula unit simply shows the lowest whole-number ratio of cations (positively charged ions) to anions (negatively charged ions) given by the formula. Sodium chloride's cation to anion ratio is one sodium cation Na+ per chloride anion Cl-, or 1 to 1.\n\nBy way of contrast, the formula H2O (for water) represents a molecule, because each molecule of water is a distinct unit.

I believe it's sodium chloride

Althouigh I am sure you mean Sodium Chloride when you say "Salt", just to be perfectly clear....there are multiple types of "salt".\nA salt is an ionic compound made up of a matal cation and a non-metal anion. Sodium Chloride ("table salt") is an example of a salt, so is Potassium Chloride and Ammonium Nitrate.\n\nWhen you dissolve a salt in water, the freezing point of the solution is lowered.  Likewise, when dissolving a salt, the boiling point of the solution is raised.\n\nBut you asked about a temperature change.\nWhen dissolving some salts, the dissolving process is endothermic...meaning that it requires enegry input to proceed.  When a endothermic process occurs, the temperature of the surroundings (this case, the water) drops.\nThere are also salts which give off energy when they are dissolved in water.  Processes which give off excess energy are called exothermic and can raise the temperature of the surroundings.\nThere are also a few (not too many) "ideal" salts which neither take in or give off energy when they dissolve.\n\nWhen the salt dissolves, if the "product" (the aqueous salt) has a lower enthalpy than the undissolved salt, the solution is said to be exothermic.  If the enthalpy increases, the solution is said to be endothermic.\n\nSalts like Potassium Chloride, Ammonium Nitrate, and several others (probably NaCl too, which you refered to) are endothermic when dissolved in water, and thus, when dissolved cause the temperature of the solution to decrease slighty.\n\nSalts like Sodium or Potassium Hydroxide are great examples of salts which are exothermic (give off energy) when they are dissolved in water.  When dissolving these salts in water, a notible increase in temperature can be observed.

Sodion Hypochlorite and Sodium Thiosulfate?  Ive never heard of Na2(s2o3)2?!  Anyways heres the balanced equation:\n\n2NaOCl + Na2S2O3 ---> Na2S2O3 + 2NaOCl\n\nPretty straight forward I guess.  Double Replacement reaction.

It's probably ethyl chloride. See link below for more info.

sodium chloride definately or cesium fluoride (not sure)-evaporation of water solution\n\npresume you mean cubic close packing

sodium chloride and water

1. sodium hypochlorite\n2. hydrogen chloride\n3. concentrated sulphuric acid\n4. oxidising it, for example with potassium manganate(VII).\n\nIf you've done the other 96, well done!

It sort of depends on what you mean by contains water, sodium chloride in water is a solution containing water where water is the solvent.  Hydrochloric acid is another, (that is just HCl dissolved in water).  Hope this helps

You can find in "Chemical Engineer's Handbook", from Perry-Chilton, graphics for density of water + NaCl solution vs. %w/w of NaCl. The NaCl concentration is 3.5%

Na+ and OH- you are dissolving a salt\n\nby the way, i am getting a phd in chem, so trust me. also, there are tons of answers in there that are totally bullshit.

The balanced solution is nothing else than a special physiological salt solution.  Near the sodium chloride it generally contains CaCl2, KCl, potassium and sodium-phosphate, Mg-salt(chloride or sulphate), sodium hidrocarbonate.\nAs additional component it may contains some glucose and/or phenol red as a pH indicator.
