A car battery contains sulphuric acid. Swati has taken this acid using a dropper and placed it in the bottle shown in the adjoining diagram. The bottle has some aluminium foil. After the addition of acid, a colourless gas is evolved which is collected by placing a balloon around the mouth of the bottle.
Answer the following now:
i) Aluminium is a ____________.
ii) The formula of Sulphuric acid is__________.
iii) The formula of Aluminium Sulphate is___________.
iv) The chemical reaction is given below in word equation: Now write the same using symbols.
Aluminium $+$ Sulphuric acid $\to$ Aluminium Sulphate $+$ Hydrogen gas

Answer 1

(i) Aluminium is metal.

(ii) $H_{2}S{O}_4$.

(iii) $A{l}_2(S{O}_4{)}_3$.

(iv) $2Al+3H_{2}S{O}_4⟶A{l}_2(S{O}_4{)}_3+3H_2$
