Dr. Rajendra K. Gupta

It is not clear for what purpose you want to make solution .At room temperature it s rate is very very low. You may call it slow leaching. That is why silica is available in underground water.

Hot water is one option to accelerate dissolving rate.

Second way is using sodium bicarbonate and get these reacted with water. More details your college chemistry technician may give
