Which one of these salts will form an acidic solution upon dissolving in water?

Select one:

a. LiBr b. NaF c. NH4Br d. KOH e. NaCN

C. NH4Br

weak base and strong acid = acidic salt

NH4Br is an acidic salt. It will form an acidic solution, dissolving in water.

(Option C)

Explanation:

Step 1: Data given

Salt is a neutral substance whose aqueous solution does not affect litmus.

Salts are formed when an acid reacts with a base.

To determine the salt whether it is acidic, basic or neutral we have to look at the acid and base that form the salt.

When the salt is formed by strong acid and weak base ... There is a Acidic salt - formed.

When the salt is formed by strong base and weak acid, There is a Basic salt-

When the salt is formed by strong acid and strong base. There is formed a Neutral salt-

LiBr is a neutral salt Lithium bromide is precipitate when dissolved in water.

KOH is a neutral salt as well. It is not an acid of any type, weak or strong, since KOH does not contribute any protons to solution.

KOH is a salt since it is composed of inorganic ions and forms a solid in the absence of any solvent. The two ions (K + and OH-) completely ionize in water. So KOH is both a strong base and a salt.

NaF is the salt of a strong base, NaOH, and a weak acid, HF. This means its a basic salt

NaCN is also a basic salts since it produce hydronium ions OH - in aqueous solution.

NH4Br is the salt of a weak base (NH3) and a strong acid (HBr), so the salt is acidic

NH4Br is an acidic salt. It will form an acidic solution, dissolving in water.
