(a) What happens when ethanoic acid reacts with sodium hydroxide? Write equation of the reaction involved.
(b) What happens when vegetable oils are hydrogenated? Name the catalyst used.
(c) What is the advantage of detergents over soaps for washing clothes? Also state one disadvantage.
(a) Ethanoic acid reacts with sodium hydroxide to form a salt called sodium ethanoate and water.
The chemical equation of the reaction is given below:
$CH_3COOH + NaOH → CH_3COONa + H_2O$
(b) When vegetable oil is hydrogenated at room temperature, a saturated product like ghee is formed (semi-solid).
The catalyst used is nickel.
(c) Advantages of detergents over soaps:
- Detergents can be used with hard water, while soaps cannot be used with hard water.
- The cleansing action of detergents is stronger than soaps.
