One such solution can be made by mixing 50 milliliters of 0.1 molar potassium hydrogen phthalate with 0.1 milliliter of 0.2 molar hydrochloric acid, then diluting this mixture to a total volume of 100 milliliters. This is from theHandbook of Chemistry and Physics, 66th Edition, page D-145. This is, of course, not the only correct answer to this question.
100 times. (10^2)
100,000 times more acidic
A PH of 4 makes the solution acidic
Is always basic.
-log(10^-4 M) = 4 14 - 4 = 10 pH
The main difference between pH 4 and pH 6 is the concentration of hydrogen ions in the solution. A pH of 4 indicates a higher concentration of hydrogen ions compared to a pH of 6, which means the solution with pH 4 is more acidic than the solution with pH 6.
a pH of 4 is most acidic than a solution with a pH of 5. In general, the lower the pH, the more acidic the solution is.
The pH of the second solution must be neutral (pH 7), as mixing an acidic solution (pH 4) with a basic solution (pH 7) would result in a pH closer to 7. This indicates that the pH of the unknown solution is around 7 to yield a final pH of 5 when mixed with the pH 4 solution.
A solution which has a pH lower than 7 is a acid.
The pH of a solution is a measure of its acidity or basicity. To calculate the pH from the hydroxide concentration, you would first need to convert the concentration to a pOH value using the equation pOH = -log[OH-]. Then, you can calculate the pH using the relationship pH + pOH = 14.
The concentration of hydroxide ions (OH-) can be calculated from the pH using the formula: [OH-] = 10^(14 - pH). In this case, for a solution with a pH of 10, the concentration of OH- ions would be 10^(-4) M.
The pH is 3,44.
