Question

Consider the incomplete reaction below.

NaOH + X mc005-1.jpg NaCH3COO + H2O

What is X in this reaction?
NH4OH
H3PO4
H2CO3
CH3COOH

Answer 1

x is CH3COOH. Beacuse its makes the equation balanced

Answer 2

NaOH + X → NaCH3COO + H2O

In the incomplete reaction above x is CH3COOH ( acetic acid)

Explanation

• carboxylic acid react with metal hydroxide to form salt and water.

• sodium hydroxide (NaOH) react with acetic acid to form sodium acetate ( NaCH3COO and water H2O.

NaOH + CH3COOH → NaCH3COO (salt) + H2O
