Asked by Bobby
Hey, can you help me on this last question. I don't understand how I can figure it ouyt without any indicators or solutions. Please help!
13. Three solutions labelled A, B, and C are known to have pH values of 4.0, 6.5, and 8.0. Write an experimental design including diagnostic tests with only two indicators to identify the pH of all three solutions.
Thanks!
Find an acid indicator that show pH 5 and below. Find a base indictor that shows 7 and above.
Those two indicators will test for all the given pHs...think on it.
