Sodium nitrate has a solubility of 92.1 g/100 ml of water at 20°C. Calculate the solubility product.

Expert Solution

solubility = 92.1g/100ml

= 92.1g/100*10^-3L [ 1ml = 10^-3L]

= 92.1g/0.1L

= 921g/L /85g/mole [ gram molar mass of NaNO3 = 85g/mole]

= 10.83g/L

NaNO3 ----------------> Na^+ + NO3^-

s s

Ksp = [Na^+][NO3^-]

Ksp = s*s

Ksp = 10.83*10.83 = 117.28 >>>>answer
