Answer 2

Answer:

If a few drops of a concentrated acid accidentally spill over the hand of a student, wash the hand immediately with plenty of water and apply a paste of sodium hydrogen carbonate.

Water will dilute the acid and wash it out. Any remaining acid will be neutralized with sodium hydrogen carbonate. This will minimize the effect of acid and damage to the skin.
