Solution A has a pH of 8 and solution B has a pH of 11. Which statement is true?

Solution A has a pH of 8 and solution B has a pH of 11. Which statement is true?

• A. Solution A is 1000 times more acidic than solution B
• B. Solution A is an acid and solution B is a base
• C. Solution B is an acid and solution A is a base
• D. Solution B is 1000 times more acidic than solution A

Answer: (A)

The correct statement regarding the pH levels of the two solutions is that solution A is 1000 times more acidic than solution B. This is based on the pH scale, which is logarithmic. Each whole number change on the pH scale represents a tenfold difference in acidity or alkalinity. In this case, solution A has a pH of 8, and solution B has a pH of 11. The difference between these two pH values is 3 (11 - 8 = 3). Since each incremental unit on the pH scale represents a tenfold change, a difference of 3 means that solution A is ten times more acidic than solution B for each unit. Therefore, because the scale is logarithmic: - From pH 8 to pH 9 is 10 times more acidic. - From pH 9 to pH 10 is another 10 times. - From pH 10 to pH 11 is yet another 10 times. Multiplying these differences gives us 10 x 10 x 10, which equals 1000. Thus, solution A, with a pH of 8, is indeed 1000 times more acidic than solution B,
