Answer:
Synthetic Method: Acids are prepared by direct combinaion of elements
Equation: H2+C1-------> 2HC1
By Dissolving acidic oxides into water: Some oxides dissolve in water to give acids
Equation: SO3+H2O-------> H2SO4
By the action of an acid on the salt of another acid: An acid having a higher boiling point can react with the salt of an acid of lower boiling point to produce an acid.
Equation:H2SO4 + NaC1-------->NaHSO4 + HC1
