What is acids? Give any two examples.
Acids are those chemical substances that gives hydrogen ions when dissolved in water.
For example: HCl -----> H+ + Cl-
H2SO4 -----> 2H+ + SO4--
Complete and balance the given incomplete equation.
i. Hcl + KoH ----------> H2O + Kcl
ii. 2KoH + H2SO4 -----------> K2SO4 + 2H2O
iii. CuO + H2SO4 ----------> CuSO4 + H2O
iv. 2NaOH + H2SO4 ---------> Na2SO4 + 2H2O
v. H2SO4 + Cu(OH)2 ---------> CuSO4 + 2H2O
