Solution Steps

Step 1: Understanding the Role of a pH Indicator

A pH indicator is a chemical compound that changes color depending on the pH level of the solution it is in. This change in color allows scientists to determine whether a solution is acidic, neutral, or basic.

Step 2: Determining the Nature of Measurement

The change in color provided by a pH indicator does not give an exact numerical value of the pH. Instead, it provides a visual cue that can be compared to a color chart to estimate the pH range.

Step 3: Choosing the Correct Term

Since a pH indicator provides an estimate of the pH based on color change rather than an exact numerical value, it is considered a qualitative measurement tool.

In a lab, silver nitrate, AgNO3, is dissolved in water until no solid is observed in the container. Then, a solution of sodium chloride, NaCl , is added to the container. When you combine these aqueous solutions, there is no noticeable change in temperature; however, a solid precipitates and there is a slight change of color. Which statements about the lab experiment involving silver nitrate and a sodium chloride solution are true? - The color change of the solution indicates a chemical reaction occurred. - A chemical reaction did occur when the solutions were combined. - The lack of temperature change indicates a chemical reaction didn't occur. - The initial disappearance of silver nitrate in water indicates a chemical reaction occurred. - Formation of a solid indicates a chemical reaction occurred. - A chemical reaction occurred when silver nitrate was added to water.
