Add the thermometer and pH meter by click the right bottom of the mouse while the cursor at the beaker then select the two from the popup menu, and while gently stirring, determine the pH of the solution Acidity measurement with indicators 1. Set up two 50 mL test tubes.2. Label one as an Acid “A” and one as a Base “B”3. Place 35 mL of the appropriate stock solution (i.e. 0.1 M HCL or 0.1 M NaOH) into each test tube.4. Add 5 drops of an indicator into each test tube.5. Record the resultant color for the acid and base.6. Repeat for the other 4 Acid - Base Indicators Titration curve and end point determination to the Unknown HCl
