Select the items that have a ph level between 5 and 8

Although this question is vague, I will answer it to the best of my ability. 

Substances between these pH levels are slightly acidic and basic. Considering water's pH is 7, some items that have pH's between these specs are black coffee, urine, water, and seawater, in that order.
