pH scale
The pH scale measures how acidic or alkaline (basic) a solution is.
The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.
an acid The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.
It indicates the concentration of H+ ions in an aqueous solution. It measures the acidity or alkalinity of a liquid. A pH of 7 (green with universal indicator) denotes Neutral. Anything below that is acidic, and anything above it is alkaline or basic. For everyday use, the pH scale goes from 1 (red) to 14 (purple). *The pH scale measures the concentration of H+ ions (or the acidity/alkalinity) in a solution. It is found by log-1 [H+], and ranges on a scale from 1 to 14 with 1 being the most acidic solution, 14 being the most basic solution, and 7 being neutral.
litmus paper. it changes color depending on the amount of hydrogen ions present in the solution. higher amount of H+ ions, its acidic and will have a lower number on the pH scale. and vice versa for basesAdded:Comment:An indicator for pH, like lithmus paper, can only tell IF a solution is acidic or basic, it can NOT measure HOW acidic (or basic) it is.The best measurement is done in the electro-chemical way: pH-measure device (pH-meter) on the '0 to 7 to 14' scale: (arbitrarely classified, based on experience)pH 0 - 2: very - rather strong acidicpH 3 - 6: rather weak - very weakly acidicpH = 7 : neutralpH 8 - 10: very weak - rather weakly basicpH 11 - 14 rather strong - very strong basic

The pH scale measures how acidic or basic a substance is.
The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.
The pH scale measures how acid something is. It goes from 1 to 14, 1 being the most acidic and 14 the least acidic.
The pH scale measures how acidic or basic a substance is.A pH less than 7 is acidic, and a pH greater than 7 is basic.hence a level of 5 is acidic.
an acid The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.
pH is measured on a logarithmic scale of 1 to 14. 1 is the most acidic, and 14 is the most alkalinic. An acidic substance has a high amount of H+ ions and an alkalinic substance has a high amount of OH- ions.

pH Scale:
Basic, they have a very low acidity on the pH scale.
