Homework Answers
Solution::
A) Acid-base reaction:
In this type of reaction, an acid is reacted with a base to produce salt amd water. It is also known as neutralization reaction.
For example:
HCl + NaOH = NaCl + H2O
B) Displacement reaction:
In this type of reaction, an element displaces another element during a chemical reaction.
Zn + 2HCl = ZnCl2 + H2
C) Oxidation-reduction reaction:
In this reaction, an element is oxidized and another element is reduced during the course of reaction.
Zn + CuSO4 = ZnSO4 + Cu
D) Weak electrolytes:
A weak electrolyte is the type of electrolytes which is weakly dissociated in aqueous solution.
For example ': Acetic acid ( CH3COOH)
