Which of the following pairs lists a substance that can neutralize Ca(OH)2 and the salt that would be produced from the reaction
Anarel [2989]

Answer:

HCl and CaCl2

Explanation:

Calcium hydroxide acts as a base, thus requiring an acid for neutralization.

HCl functions as an acid, which can neutralize calcium hydroxide when they react together.

The resulting salt will be calcium chloride (CaCl2).

The interaction between calcium hydroxide and HCl yields Ca(OH)Cl and CaCl2.

Here, Ca(OH)Cl exists as a solution and calcium chloride serves as a base.

I hope this response assists you.
