Going from a ph of 4 to a ph of 6 represents
WebpH is a logarithmic scale. This means that for each one-digit change in pH, the acidity (H + concentration) changes by 10 times. For example, a solution with a pH of 4 has 10 times more H + than a solution with a pH of 5. A solution of pH 3 will have 100 times more H + (it is 100 times more acidic) than a solution of pH 5. WebNov 3, 2024 · pH 4 represents an acidic pH because acidic range is a range with pH equal in the interval 0 < pH < 7 and basic range is a range with pH equal in the interval 7 < pH < 14 .So, the answer for your question is 4 because it is in the interval 0 < pH < 7.
