What acid and what base would you choose to prepare the salt potassium perchlorate (kclo4)?

Answer : The perchloric acid and potassium hydroxide base is used to prepare the salt of potassium perchlorate,

Explanation :

when the perchloric acid react with the potassium hydroxide as a base to form a salt of potassium perchlorate,

The balanced chemical reaction will be,

By the stoichiometry, we can say that 1 mole of perchloric acid react with the 1 mole of potassium hydroxide base to give 1 mole of potassium perchlorate and 1 mole of water as a product.

Hence, the perchloric acid and potassium hydroxide base is used to prepare the salt of potassium perchlorate,

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
