Question

What is the general word equation for salt formation by neutralization?

metal + acid → salt + water
nonmetal + acid → salt + water
acid + base → salt + water
metal + base → salt + water

Answer 1

Answer: acid + base → salt + water

Explanation: Neutralization is a type of double displacement reaction in which exchange of ions take place. Neutralization is a chemical reaction between an acid and a base where ions exchange and lead to formation of salt and water.

`HCl(aq)+NaOH(aq)\rightarrow NaCl(aq)+H_2O`

HCl is an acid which donates
`H^+` ions when dissolved in water.
`NaOH` is base which donates
`OH^-` ions when dissolved in water. They combine to form
`NaCl` which is salt and
`H^+` and
`OH^-` ions combine to form water
`H_2O`.

Answer 2

The correct option is ACID + BASE = SALT + WATER
Neutralization is a chemical reaction in which acid react with base and the products formed are salt and water. Acid and base are corrosive chemicals, especially the strong ones, but during the process of neutralization the two react together to produce salt and water, which are neutral substances.
