​

Answer 1

Answer:

Ph scale determines whether a compound is acid or base with presence of certain dye. if ph scale ranges from 1 to 6 then compound is acid but if it ranges from 8 to 14 it is a base and at 7 it is neutral

Answer 2

pH is the measure of acidity and basicity of a substance.

Explanation:

• pH is the measure of the hydrogen or hydroxide ions and determines whether a substance is acidic, basic or neutral.
• This scale consists of numbers from 0 to 14, where 7 is the middle one and is neutral.
• If we move towards the left of 7, the acidity increases. But if we move towards the right of 7, the basicity increases till 14.
• The strong acid solution has a high concentration of hydrogen ions, whereas the strong base solution has a high concentration of hydroxide ions.
