PH LEVEL?
A LIQUID CAN BE ACIDIC, NEUTRAL, BASIC ?
Whether a liquid is acid or base depends on the type of ions in it. If it has a lot of HYDROGEN (H) in it, then it is ACIDIC. If it has a lot of HYDROXIDE ions in it, then it is basic or alkaline.
Almost all liquids are either acids or bases to some degree . Some of them can be neutral though.

PH SCALE
Scientists use a pH scale to measure how acidic or basic a liquid is. pH is a number from 0 to 14. From 0 to 7 are acids, with 0 being the strongest. From 7 to 14 are bases with 14 being the 0 to 14. From 0 to 7 are acids, with 0 being the strongest. From 7 to 14 are bases with 14 being the strongest base. If a liquid has a pH of 7, it's neutral. This would be something like distilled water.

WHAT IS A PH INDICATOR ?
A PH indicator is
- a chemical compound that is used to visually determine if a solution is acidic or basic,
- a chemical detector for hydroxide (HO+) or hydrogen (H+) molecules. PH indicators change color depending on the PH of the solution they come in contact with.
The indicator changes color depending on the PH of the solution it is testing.
Examples of PH indicators:
Phenolphthalein, Phenol Red, Methyl yellow and Bromophenol blue
