Answer:
The answer is 30 g of sodium hydrocarbonate
Explanation:
This is a acid-base reaction, so in order to neutralise the spilled acid, the mol of spilled acid should be calculated.
M = n / V => n = M x V = 0.028 x 6.2 = 0.1736 mol
Since 1 mol of sulfuric acid generates 2 mol of H⁺, so the mole of H⁺ is 0.3472 mol or 0.35 mol with two significant figures.
To neutralized the acid, we need at least the same mole of base, so we need at least 0.35 mol of NaHCO₃, which can be converted to its mass at 29.4 g.
Since the answer need to be expressed in two significant figures and also need to make sure to neutralize all the acid, so we will use a little excess base. The answer is 30 g.

As there is the increase in Oxidation number from +1 to +2. Hence, the correct Option (A) i.e, 1 to +2,
<h3>
What is Oxidation ?</h3>
Oxidation doesn't necessarily have anything to do with oxygen.
- Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction.
- When oxidation occurs, the oxidation state or oxidation number of the chemical species increases.
- Oxidation doesn't necessarily involve oxygen! Originally, the term was used when oxygen caused electron loss in a reaction.
Hence, Option (A) indicates the oxidation as there is the increase in Oxidation number from +1 to +2.
