what is differentation of alkali and base?

alkalies are water soluble bases.\nths means all alkalies are bases but all bases are not alkalies

It's a salt - ammonium acetate. Ammonium is an acid, but the acetate ion is actually alkaline.

In general science terms, an acid is a molecule or ion that, when placed in water, will give up a hydrogen ion (H+) to a base, or accept an unshared pair of electrons from a base. \n\nA base is a substance which dissociates (separates) in aqueous solution to yield hydroxyl ions (OH-) which react with an acid to form a salt.\n\nAcids and bases react with one another in a neutralization reaction to form a salt. This is also the basis of buffers.\n\nIf you want to get down the simplest definitions: \n\nAn acid is a solution that has more free hydrogen ions (H + ) than hydroxyl ions (OH - ) and a pH less than 7.\n\nA base is a solution that has less free hydrogen ions (H + ) than hydroxyl ions (OH - ) and a pH of more than 7.

Technically with molar amounts being equal, an acid and a base react in what is called a "neutralization reaction"...\n\nie:\n\nHCl + NaOH ---> NaCl and water\n\nBasically you get a salt and a water.

Apart from the precipitation reactions (AgCl and BaCO3 form insoluble compounds, although HCl will dissolve BaCO3), there is flame colouring for identifying the alkali and earth alkali metals (Na yellowish orange, Li reddish, Ba green), there are pH measurements (HCl acidic, NaOH and Na2CO3 basic, rest neutral), and you need to test an oxidant to identify the sugar solution. This ought to give you a matrix which gives only one possible identification for each test (with deionized water failing all tests).

Most acids form ions in solutions by _protolysis_ (transferring a hydrogen ion to the solvent), and most bases form ions in solution by disassociation (if they contain OH-ions) or by accepting a hydrogen ion from the solvent.\n\nExample: Na3PO4 + H2O --> 3 Na+ +HPO4(2-) + OH-

The word alkali comes from the Arabic word for "ashes," where the oxides of these metals were first found. Alkali is now used as another word for base (see acids and bases); when the ashes containing the oxides of the alkali metals are dissolved in water, a base is formed. For example, sodium oxide dissolved in water yields sodium hydroxide, or lye.

I think this is how you do it:\nacid and base is measured in terms of pH and pOH. as you know, the H makes it acidic and the OH makes it basic, and if you mix an H and OH, you get water, which is to say it was neutralized.\nSo, let's say you have HBr with a pH of 4. You that pH is a measure of the concentration of H present in the mixture. So, to get the actual number you do -10ph, and you'll get a number like 10^-5 or something. So, to neutralize that many Hs, that's how many OH's you need. so, you'll need a pOH 4, which is the same thing is a pH of 10 (pOH = 14 - pH). \nhope that helps, good luck. and read the book, and do some of hte exercised in the book.

Let's take potassium representing group 1.  All the others will do the same thing.  Here is the reaction:\n\n2K(s) + 2HCl(aq) --> 2KCl(aq) + H2(g)\n\nThe reaction for group 2 will be similar.  Let's take calcium  representing group 2:\n\nCa(s) + 2HCl(aq) → CaCl2(aq) + H2(g)\n\nHope this helps.

ok, so lithium hydroxide is a base; nitric acid is an...acid; and \n\nacid + base -> salt + water\n\nin this case, it's\n\nLithium hydroxide + Nitric acid -> lithium nitrate + water\n\nLiOH + HNO3 -> LiNO3 + H2O\n\nBest wishes!

Cations are particles with a positive charge, while anions are particles with negative charge. Cations are formed when an atom loses electrons, while anions are formed when an atom gains electrons. Among the atoms, the alkali metals (Group 1) and alkaline-earth metals (Group 2) are the most reactive metals, having one and two valence electrons, respectively. Therefore, metals lose that electrons and form cations.

You missed to write 'metals'. This is customary.!!!\n\nAll answers are relevant.\n\nmurthy seems to be more relevant to the question.\n\nReview in the following way:\n\nOne thing common with 1A & 2A group is there nature to form alkalies with water; so they are alkaline in nature.\n\nThe second thing common is that they all are metals so they are alkaline metals.\n\nAn additional aspect only to 2A group is that the members of the group are normally more abundent in mineral form (in the earth crust) so to distingwish with the other alkaline metals they are referred as alkaline earth metals.

basically, we call it an acid if the compound can be resolved into existing H+ and OH- ions. if this can be resolved then it is called acid and base. \n\nThis is pH. amount of H+ ions and amound of OH- ions. more the amount of free H+ ions in the compund more the acidic nature.\nmore the OH more the basic nature and less is the acidic nature.\n\nIt also depends on the medium in which the compound is present. some act as acids in aqueous medium. and so on....\n hope it was helpful. \nAny doubts u can ask further.
