What's Soluble And
What's Not
S= Soluble in water.
I= Insoluble in water.
P= Slightly soluble in water.
X= Compound does not exist or decomposes in water.
General rules of solubility
1. All ammonium, potassium and sodium compounds are soluble in
water.
2. All acetates, chlorates and nitrates are soluble in water.
3. All chlorides are soluble in water except those of silver,
mercurous mercury, and lead.
4. All sulphates are soluble in water except those of barium
and lead, calcium, strontium And Silver sulfates are only slightly soluble.
5. Carbonates, phosphates, oxides, silicates, sulfides, and
sulphates are generally insoluble with the exceptions of those of ammonium,
potassium and sodium.
6. All hydroxides are insoluble except those of ammonium,
potassium, sodium, barium calcium and trontium. those of barium, calcium and
strontium are only slightly soluble in water.
