Detailed explanation-1: -Since a pH of 3 is three numbers higher than a pH of 6, we can find the change in acidity by taking 10 to the third power. The solution with a pH of 3 is 1000 times more acidic than the solution with a pH of 6.
Detailed explanation-2: -Therefore, the solution with pH 3 is 1000 times more acidic than the solution with pH 6.
Detailed explanation-3: -Each whole pH value below 7 is 10 times more acidic than the higher value and each whole pH value above 7 is 10 times less acidic than the one below it.
Detailed explanation-4: -The lower a substance’s pH, the more acidic it is. Each whole pH value below 7 (the neutral point) is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6.
Detailed explanation-5: -Each whole pH value below 7 is 10 times more acidic than the next higher value, meaning that the concentration of hydrogen ions is 10 times as great.
