Complete the following reactions:
`overset((A))"Glyoxal" overset(1. NaOH)underset(2.H_(3)O^(o+))rarr (B)`

Explanation

To complete the reaction of Glyoxal (A) with sodium hydroxide followed by acidification, we will follow these steps:

### Step 1: Identify Glyoxal
Glyoxal is an organic compound with the formula \( C_2H_2O_2 \) or \( OHC-CHO \). It has two aldehyde groups.

### Step 2: Reaction with Sodium Hydroxide (NaOH)
When Glyoxal is treated with sodium hydroxide, it undergoes a reaction known as the Cannizzaro reaction. This reaction occurs in the absence of alpha hydrogen atoms.
