Question

1.A) what are bases?

B) Explain their characteristic properties​

Answer 1

hey

______________________________

A.Arrhenius proposed in 1884 that a base is a which dissociates in aqueous solution to form hydroxide ions OH-. ... A soluble base is called an alkali if it contains and releases OH− ions quantitatively. Metal oxides, hydroxides, and especially alkoxides are basic, and conjugate bases of weak acids are weak bases.

B.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. The strength of bases is measured on the pH scale.

Answer 2

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.

CHARACTERISTICS PROPERTIES OF BASES-

1.Bases may or may not be soluble in water Bases that can dissolve in water are called alkalis. Some examples of soluble bases or alkalis are sodium hydroxide, potassium hydroxide, and calcium hydroxide.

Like acids, bases can be strong or weak.

Strong bases are very corrosive and can burn the skin.
