Question

what is ph ?? explain with example​

Answer 1

Explanation:

pH is a measure of hydrogen ion concentration, a measure of the acidity or alkalinity of a solution. The pH scale usually ranges from 0 to 14. Aqueous solutions at 25°C with a pH less than 7 are acidic, while those with a pH greater than 7 are basic or alkaline

Answer 2

Answer:

In chemistry, pH (/piːˈeɪtʃ/) (abbr. power of hydrogen[1] or potential for hydrogen[2]) is a scale used to specify how acidic or basic a water-based solution is. Acidic solutions have a lower pH, while basic solutions have a higher pH. At room temperature (25°C or 77°F), pure water is neither acidic nor basic and has a pH of 7.
