Question

how to determine if a salt is basic or acidic or neutral just by seeing the formula?​

Answer 1

Answer:

Explanation: inorganic chemistry will always give exceptions. ;) .. But mostly metal salts are basic and non metal salts are acidic

Answer 2

There is a process by which we can determine if a salt is basic or acidic or neutral just by seeing the formula .

• We can describe it by some example

we are taking three different types of salts and those salts are NaCl,FeCl2,KF

and now when each and every salts will react with water , they will form a acid(strong/weak) and a base(strong/weak).And by seeing it we can determine that it is acidic or basic or neutral in nature.

•First of all when NaCl reacts with water it forms HCl which is a strong acid and NaOH which is a strong base

Nacl +H2O —›HCl+NaOH= strong acid+strong base = neutral

so NaCl is neutral in nature

• When FeCl2 reacts with H2O ,it forms HCl which is strong acid and Fe(OH)2 which is weak base

FeCl2+ H2O —›HCl + Fe(OH)2= strong acid+weak base= Acidic

so FeCl2 is acidic in nature

• When KF reacts with water ,it forms HF which is weak acid and KOH which is strong base

KF+ H2O—› HF+ KOH= weak acid+ strong base= Basic

so KF is basic in nature.

thus we can determine the perticular compound is acidic or basic or neutral.
