You are studying a clear solution and you added the pH indicator methyl violet. The colour range of the indicator methyl violet in a clear solution when changing from acidic to basic is yellow (pH 0) to blue purple (pH 1) to violet (pH 2). You initial pH of the solution when tested with a pH meter is O.2. You are going to add 250 drops of 0.1 M HCI. Please select the most appropriate answers to the following two questions. What is the initial colour of the solution at pH 0.2? What is the colour of the solution and what will the pH be after the addition of the HCI? Select 2 correct answer(s) The colour of the solution after the addition of HCI will be clear and the pH will be less than 0.2. The colour of the solution after the addition of HCI will be violet and the pH will be higher than 0.2.
The pH scale was designed to make it convenient to express hydrogen ion concetrations that are small in aqueous solutions. The definiton of pH is in terms of base 10 logarithms. pH : - log [H*] where H*] is the hydrogen ion concentration. a. If the hydrogen ion concentration in a solution is 1.38 x 10- mol/L, the pH is b. If the pH of a solution is 3.590, the hydrogen ion concentration is mol/L.
