1. How to tell if a compound is soluble with its solubility of 359g/L and that it dissolves at 25C in 1L of water?

Following the rules of solubility and insolubility determine if the following compound is soluble in water.

Na₂CO₃

(Group IA and ammonium compounds are soluble)

(CO₃^2- Most carbonates are insoluble)

Solubility in 5% NaHCO3 (aq) and 5% NaOH(Aq)
Compounds that dissolve in sodium bicarbonate (Why?), a weak base,are relatively strong acids. Compounds that dissolve in NaOH(Why?), a strong base, may be either strong or weak acids. Thus,once can distinguish weak and strong acids by determing theirsolubility in both strong and weak bases. Some examples of strongeracids that are soluble in both NaOH and NaHCO3 are: Carboxylicacids (why stronger?), o/p-substituted di and trinitrophenols (whystronger?)

Using table to determine whether or not 120.0g ofCaCl₂will dissolve in 200mL of water at roomtemperature. Give yourreasoning.
