1)

What is the density of the solution of sulphuric acid as an electrolyte in the lead accumulator?


A) 1.5 $gmL^{-1}$

B) 1.2 $gmL^{-1}$

C) 1.8 $gmL^{-1}$

D) 2.0$gmL^{-1}$

Answer:

Option B

Explanation:

An aqueous solution of sulphuric acid i.e, 38% by weight or having a density of 1.30 g mL-1is used as an electrolyte in lead accumulators,It is consumed during discharging and when  the concentration of H2SO4 falls to 1.20 g mL-1 , it requires recharging.Thus, the most suitable option is (b)
