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