# Solubility curve

Chemistry Level pending

The above are the solubility curves of ammonia(NH$$_3$$) and magnesium sulfate(MgSO$$_4$$). Which of following explanations is correct?

a) The molality of the two solutions is the same at point P.

b) (A) is the solubility curve of magnesium sulfate.

c) If the temperature of saturated solution (B) is decreased from T$$_2$$ to T$$_1$$, then the solution begins to precipitate the excess amount of solute.
