Concept Introduction:

Soluble compounds:

• Compounds of the elements from Group 1 are soluble.
• Ammonium compounds, chlorides, bromides, iodides are soluble except for the cation being ${\text{Ag}}^{\text{+}}$, ${\text{Hg}}_{\text{2}}{}^{\text{2+}}$, and ${\text{Pb}}^{\text{2+}}$.
• Nitrates, acetates, chlorates, and also perchlorates are soluble except for the cation being ${\text{Ca}}^{\text{2+}}$, ${\text{Sr}}^{\text{2+}}$, ${\text{Ba}}^{\text{2+}}$, ${\text{Pb}}^{\text{2+}}$, ${\text{Hg}}_{\text{2}}{}^{\text{2+}}$, and ${\text{Ag}}^{\text{+}}$.
