JEE Main 2026 Chemistry question
Aqueous HCl reacts with to form , and . What is the weight (in g) of liberated when 8.7 g of is reacted with excess aqueous HCl solution? (Given Molar mass in g mol Mn = 55, Cl = 35.5, O = 16, H = 1)
Answer: (1)
Solution
MnO_2 + 4HCl \to MnCl_2 + Cl_2 + 2H_2O. Moles of , giving 0.1 mole , weight g.
