Question:medium

Excess of carbon dioxide is passed through 50 mL of 0.5 M calcium hydroxide solution. After the completion of the reaction, the solution was evaporated to dryness. The solid calcium carbonate was completely neutralised with 0.1 N hydrochloric acid. The volume of hydrochloric acid required is (Atomic mass of calcium = 40)

Show Hint

Equivalents of Acid = Equivalents of Base.

A solenoid of length $50~\mathrm{cm}$ and a radius of cross-section $1\mathrm{cm}$ has 1000 turns of wire wound over it. If the current carried is 5A, the magnetic field on its axis, near the centre of the solenoid is approximately (permeability of free space $\mu_{0} = 4\pi \times 10^{-7}\mathrm{T}\cdot \mathrm{m / A}$)
