Explanation:
Detailed explanation-1: -A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value.
Detailed explanation-2: -Explanation: Since pH is a logarithmic scale, a change in pH of 1 results in a ten-fold change in the concentration of H+, which would be a ten-fold change in acidity/basicity .
Detailed explanation-3: -Correct answer: 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.
