Given ph = 6.75,
is this acidic, basic or neutral?
how do you know?

Acidic.

Explanation:

pH is a logarithmic function of [H+]:

pH = −log[H+]

pH is usually (but not always) between 0 and 14. Knowing the dependence of pH on [H+], we can summarize as follows:

If pH < 7, then the solution is acidic.

If pH = 7, then the solution is neutral.

If pH > 7, then the solution is basic.

Given pH is 6.75 so it is acidic.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

elements make up everything, and they combine to make compounds.

the answer is c
