# What type of solution forms if 50g of Pb(NO_3)_2 are dissolved in 100g of water at 20 degrees C?

$P b {\left(N {O}_{3}\right)}_{2} \left(s\right) r i g h t \le f t h a r p \infty n s P {b}^{2 +} + 2 N {O}_{3}^{-}$
We know that the solution is saturated if equilibrium quantities of $P b {\left(N {O}_{3}\right)}_{2}$ are in solution. You will have to look up the solubilities of lead nitrate at the given temperature to see that this is indeed the case.
