Which characteristic best identifies an arrhenius base? it must donate electrons to form a covalent bond. it must accept protons from an acid. it must generate hydroxide ions in water. it must form a conjugate acid after reacting.

Option C= It must generate hydroxide ions in water

An Arrhenius base is a substance that, when dissolved in an aqueous solution, increases the concentration of hydroxide, or OH-, ions in the solution. An aqueous solution is a solution that has water present in it.

A base, sodium hydroxide, is added to an aqueous solution.  It dissociates into sodium, Na+, and hydroxide, OH-, ions. Because the hydroxide ions are released in the aqueous solution, the hydroxide concentration increases; therefore, NaOH is an Arrhenius base.

NaOH (s)  → Na+ (aq) + OH– (aq)

law of conservation of matter

the answer is the first option

explanation:

just googled it m8. not that hard
