Question

Which substances will make a salt when combined? Vinegar and antacids Soda and wine Soap and ammonia Fertilizer and detergent

Answer 1

Answer is: vinegar and antacids.

Neutralizationis is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH) and a base (in this example antacid, aluminium hydroxide, magnesium hydroxide or some other base) react quantitatively with each other.

Balanced chemical reaction of vinegar and antacid:

2CH₃COOH(aq) + Mg(OH)₂(aq) → (CH₃COO)₂Mg(s) + 2H₂O(l).

Magnesium acetate ((CH₃COO)₂Mg) is a salt.

Answer 2

Salt is usually formed during neutralization reactions, that is the reaction of an acid and a base. This is illustrated as follows:

HX + YOH --> XY + H2O

where XY is the salt

From the given choices, the only pair of acid and base is:
