Answer 1

Answer:

hope this may help you.....

Explanation:

Bases are ionic compounds that produce negative hydroxide ions (OH-) when dissolved in water. Bases taste bitter, feel slippery, and conduct electricity when dissolved in water. Indicator compounds such as litmus can be used to detect bases. Bases turn red litmus paper blue.

Example:

1. sodium hydroxide, NaOH - Used in the manufacture of soaps and detergents and as the main ingredient in oven and drain cleaners.

2. potassium hydroxide, KOH - Used in the production of liquid soaps and soft soaps. Used in alkaline batteries.
