Astudent uses an indicator to measure the ph of a solution. the indicator shows a ph of 7. what must be true of this solution?

the solution contains neither hydronium ions nor hydroxide ions.

the solution has equal amounts of hydronium ions and hydroxide ions.

the solution is acidic.

the solution is basic.

The solution has equal amounts of hydronium ions and hydroxide ions.

Explanation:

From the very beginning it is clear that answer choices 3 and 4 are incorrect, as a pH of 7 means it is neutral.

The pH of anything being 7 (neutral) means it is neither an acid (1-6) nor a base (8-14).

This essentially levels things out meaning that there will be an equal amount.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
