Objectives predict the ph value of common solutions

---------------------------------------------------------------------------------------------------------------------
Objectives:
􀂇 Predict the pH value of common solutions.
􀂇 Use pH paper to determine the pH value of common solutions.
􀂇 Determine whether a common solution is acidic, neutral, or basic.
Procedure:
1. Scroll down to the bottom of this document and record the names of the solutions you will test. Predict the
pH value of each solution, and record your predictions in the Table.
2. Use pH paper to test the first solution. Click and drag the paper into the test tube, then match its color on the
scale of pH values. Use the up and down arrows on the pH Value Counter to indicate the pH value of the
solution.
3. Use separate strips of pH paper to test each of the other solutions and determine its pH. Use the up and down
arrows on the pH Value Counters to indicate the pH values of these solutions. Enter the information in the
Table.
4. When all the pH values are entered, click the Check button to evaluate your answers. If the Ph value of a
solution is incorrect, the pH value is highlighted yellow. Use pH paper to test the solution again. Use the up and
down arrows on the pH Value Counter to enter the answer. Then click the Check button again.
