Question
Suppose you want an acidic solution to carry out a chemical reaction with 2 moles of NaOH. Which sample of acid is the best choice for you. (At. wt. : S = 32, Cl = 35.5)
Options
A.1 M H2SO4 (50 Rs per lt.)
B.1 M H2SO4 (56 Rs per lt.)
C.1 M HCl (30 Rs per lt.)
D.1 M HCl (27 Rs per lt.)
Solution
For reaction with 2 moles NaOH
1M H2SO4 1 lit. volume required
1M HCl 2 lit. volume required
∴ cheapest will be 1 M H2SO4 1 lit.
1M H2SO4 1 lit. volume required
1M HCl 2 lit. volume required
∴ cheapest will be 1 M H2SO4 1 lit.
