If H2SO4 contacts the skin, it is cleaned fast with a dry cloth and then rinsed with: A) H20+vinegar
B) H2O+baking soda
C) H2O+table salt

(B) H2O + Baking soda

Explanation:

H2SO4 is commonly known as Sulfuric acid. It is a strong acid which can cause severe damage to body parts when comes in contact. If H2SO4 contacts the skin then it will be quite irritating for the skin so its better to apply water (H2O) with Baking soda.

Baking soda is of alkaline nature when it will react with H2SO4 it will undergo neutralization and the effect of the strong acid H2SO4 will be minimized.

The chemical reaction between baking soda and H2SO4 is

H2SO4(aq) + 2NaHCO3(aq) →  Na2SO4(aq) + 2CO2(g) + 2H2O(l)

Therefore the reaction is known as neutralization reaction. This aqueous baking soda reacting with Sulfuric acid neutralizes its effect and minimize its effect on the skin.
