What helps determine if a solution is a acid or basic?

Answer 1

If a solution have a higher concentration of H+ ions, then the solution is an acidic solution. If a solution has a higher concentration of OH- ions, then the solution is a basic solution.

The above is an overly simplistic and inaccurate description.

Actually it is only the concentration of a type of ion called pi-Hydronium or pH, which have the formula H2OH+. More pi-Hydronium ions (lower pH number) the solution is acidic, same number of pi-Hydronium ions as pure water (pH number exactly 7) the solution is neutral, fewer pi-Hydronium ions (higher pH number) the solution is basic.

With solvents other than water, while H+ ions might be able to form, the solution cannot be acidic or basic as pi-Hydronium ions cannot form.

Answer 2

In order for a water solution to be basic, the solute(s) within the solution all must have a pH greater than or equal to 7.1. Any substance or compound with a pH of 7.1 or higher is classified as basic, meanwhile anything lower than or equal to 6.9 is classified as acidic.

Answer 3

the amount of OH- ions are greater than the amount of H+, even if the amount of H+ is 0

Answer 4

If the pH is higher than 7 on the pH scale then it is basic. Fewer hydrogen molecules= less acidic.

Answer 5

a higher concentration of OH¯ ions than H+ ions

Answer 6

This depends on the substances dissolved; to be sure measure the pH.
