Question

In basic media, OH− ions and water are added to half

reactions to balance the overall reaction. Take the

reaction between potassium permanganate and sodium

sulfite. Balance using ion electron method:

MnO4– + SO32- + H2O → MnO2 +SO42- + OH–​

Types of chemical reaction :-

✪ Combination reaction -

Those reaction in which two or more substances combined to form a single substance, are called combination reaction.

✭ Example -

C + O2 → CO2

✪ Decomposition reaction -

Those reaction in which a compound splits up into two or more simpler substances are known as decomposition reaction.

✭ Example -

CaCO3 → CaO + CO2

✪ Displacement reaction -

Those reaction in which one element takes the place of another element in a compound, are known as Displacement reaction.

✭ Example -

CuSO4 + Zn → ZnSO4 + Cu

✪ Double Displacement reaction -

Those reaction in which two compounds react by an exchange of ions to form two new compounds are called double displacement reaction.

✭ Example -

AgNO3 + NaCl → AgCl + NaNO3
