Concept explainers
(a)
Interpretation:
The concentration of an acid and the pH of the solution should be predicted.
Concept Introduction:
The full form of pH is the potential of pH. In other words, it explains the strength of the hydrogen ion in a solution. It is given by the formula,
(a)

Answer to Problem 6E
The concentration of an acid and pH of the solution is 1.7 M and -0.23 respectively.
Explanation of Solution
Given information:
- 0.95 M NaOH
- 46 mL NaOH
- 25 mL of acid
The concentration of an acid is calculated as follows:
The pH of the solution is calculated as follows:
Therefore, the concentration of an acid and pH of the solution is 1.7 M and -0.23 respectively.

- 6. Chlorine dioxide (CIO) is used as a disinfectant in municipal water-treatment plants. It decomposes in a first-order reaction with a rate constant of 14 s. How long would it take for an initial concentration of 0.06 M to decrease to 0.02 M? [6 pts]arrow_forwardIf possible, replace an H atom on the a carbon of the molecule in the drawing area with a methyl group substituent, and replace an H atom on the ẞ carbon with a hydroxyl group substituent. If one of the substituents can't be added for any reason, just don't add it. If neither substituent can be added, check the box under the drawing area. en HO OHarrow_forwardCurved arrows are used to illustrate the flow of electrons.
