pH scale ranges from – (1) 0 - 7 (2) 8 - 14 (3) 0 - 14 (4) None

Description : pH scale ranges from – (1) 0 - 7 (2) 8 - 14 (3) 0 - 14 (4) None

Last Answer : (3) 0 - 14 Explanation: 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 ... is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the new higher value.
