Question

Which of the following statements about measurement of pH is incorrect?

a. the ph of a solution can be determined use a ph meter
b. the ph of a sultion can be determined by the indicator method
c. a ph meter ismore accurate than an indicator for determing the ph
d. many indicators are strong acids or strong bases
e. acid base indicators have different colors in solutions of differents pH

Answer 1

The incorrect statement about the measurement of pH is that a pH meter is more accurate than an indicator for determining the pH.

Step-by-step explanation:

The incorrect statement about the measurement of pH is: c. a pH meter is more accurate than an indicator for determining the pH. While a pH meter is commonly used to determine the pH of a solution and is generally more accurate and precise than indicators, it is not always the case. Some indicators can provide accurate enough results for certain applications, especially when precise measurements are not required. Indicators are often used for quick estimations or qualitative analyses. For example, pH paper is impregnated with indicators and can provide a simple way to estimate the pH of a solution by comparing the resulting color with the standards printed on the container.
