measurement to tell how acidic or basic something is• scrapbookers want items with ph of 7 or higher
a value used to express acidity of a substance. Expressed as a number on a scale of 0 to 14, with 7.0 being neutral; values less than 7.0 are acidic and values greater than 7.0 are basic. In pool and spa water, the pH level should be in the range of 7.2–7.8, with 7.4–7.6 considered ideal. (N) Potassium monopersulfate (KHSO5): a solid oxidizer used to prevent the buildup of contaminants in pool and spa water. (N)
A scale to measure the strength of an acid or alkali. pH 7 is NEUTRAL (neither acidic nor alkaline). Below pH 7 is acid, above pH 7 is alkaline.
Measurement that tells a scrapbooker how acidic or basic something is. For scrapbooking, you want to use products with a pH level of 7 or above.
Acid is measured on a level from 0-14 where 7 is neutral. A substance that has a pH level of 0 is very acidic and one with a pH of 14 is alkaline.
A measure of acidity or alkalinity as of soil, water etc. on a scale running from 1 (extreme acidity) to 14 (extreme alkalinity), equal to the negative logarithm of the concentration of the negative logarithm of the hydrogen ion in gram atoms per litre. So a pH of 5 indicates a concentration of 10-5 gram atoms of hydrogen in one litre.
Measurement that tells a scrapbooker how acidic something is. For scrapbooking, you want to use products with a pH level of seven or above. A pH Testing Pen is a pen used to test the acidity of paper. The pen mark changes colors, depending on the level of acid present.
