Question

Consider air to be a diatomic gas with average mole moasses 29g/mole. A mass 1.45kg of air is contained in a cylinder with a piston at ${27}^{0}C$ and pressure $1.5\times {10}^{5}N/m^2$. Energy is given to the system as heat and the system is allowed to expand till the final pressure $3.5\times {10}^{5}N/m^2$. As the gas expands, pressure and volume follow the relation
$V=K{P}^2$ where K is constant (R =8.3J/(mole-K)

Which solutionn. will give a white ppt. when either dil. $HCl$ or dil. $H_{2}S{O}_4$ is added to it?

Answer 1

lead nitrate as lead chloride and sulphate both are white.
