Question

Substance X present in vinegar reacts with substance Y present in the milk of magnesia. The product obtained from the reaction between X and Y is?

• A. $CuS{O}_4$
• B. $NaHC{O}_3$
• C. $NaCl$
• D. $(C{H}_3-COO{)}_{2}Mg$

Answer 1

The correct option is D

$(C{H}_3-COO{)}_{2}Mg$

Vinegar is an aqueous solution of acetic acid($C{H}_{3}COOH$). Vinegar typically contains 5–20% of acetic acid. So chemical X is acetic acid.

Milk of magnesia is a viscous, white, mildly alkaline solution of magnesium hydroxide($Mg(OH{)}_2$). So chemical Y is magnesium hydroxide.

Vinegar is made up of acid and milk of magnesia is made up of a base. A reaction in which acid and base react is called neutralization reaction. A neutralization reaction is when an acid and a base react to form water and salt. The reaction between both the chemicals is given below.

$2C{H}_{3}COOH+Mg(OH{)}_2\to (C{H}_3-COO{)}_{2}Mg+2H_{2}O$
