Me with chemistry

bases:

are generally proton acceptors

produce oh− ions in solution

are electron pair donors

may include all of these characteristics

Of course :may include all of these characteristics

Because all answers are correct :they react with acids that have H+ ions and they all have OH- ions so they can be electrons donors and produce these ions in solution

:)

The answer is may include all of these characteristics.

Explanation:

In chemistry, the term bases is used to describe substances that release hydroxide ions in aqueous solution. They are also generally proton acceptors as well as electron pair donors. Some examples of them are the hydroxides of the alkali metals and the alkaline earth metals. Due to this, the correct answer is letter D.

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

what is the question?
