Some Important Reactions Regarding Stoichiometry

Some Important Reactions Regarding Stoichiometry

Effect of Heat on Carbonate and Bicarbonate

Other carbonates decomposes to give oxides and CO₂

All bicarbonates decomposes to carbonates,CO₂,  HO₂

Effect of Heat on Chlorides, Bromides and Iodides

Generally these are not effected by heat.
Some halides of higher oxidation states changes into halides of lower oxidation state on heating.

H₂O  and haloacids (HF, HCl, HBr,HI) such as

Effect of heat on Sulphates and Bisulphates

Effect of Heat on Sulphates, Pyrosulphates and Bisulphates

Sodium and potassium sulphates are thermally stable. However other sulphates, anhydrous or hydrous, decompose to give different products. Such as

Effect of heat of Nitrates

They undergo thermal decomposition in following ways

Effect of heat on Oxide and Hydroxide

Hydroxide, and higher oxides and some metals undergo following change on heating strongly.

SOME OTHER IMPORTANT REACTIONS

SOME IMPORTANT POINTS TO REMEMBER

If a salt of strong acid and strong base (e.g. NaCl) is present in the solution it will not react with any acid or base added to the solution.
If a salt of strong acid and weak base (e.g.NH₄Cl) is present in the solution it will only react with strong base but it will not react with strong acid.

If a salt of strong base and weak acid (e.g CH₃ COONa) is present in the solution it will react only with strong acid but it will not react with strong base.
