Lab Acids and Bases: Determination of pH In this investigation we estimated the pH of divers(a) solutions utilize indicators and a pH meter. We engage five indicators methyl bolshy indicator, litmus judge indicator, Bromthymol indicator, Phenophtalein indicator and the simoleons extract indicator, and we used octet solutions to try with sever all(prenominal)y indicator. The octette solutions used where HCl, ethanoic dose (HC2H3O2), ammonia irrigate (NH3), NaOH, lean urine, baking soda, poove and vinegar. We began boiling g eachant rob as the color extracts into the water leaving it identical an indicator, and hence we separated eight bear witness renders and added tap water to each one. After we added Methyl ablaze(p) indicator to the eight analyse tubes and record its color with tap water, to each test tube except one we added the distinguishable solutions and recorded the changes in color. We did the equal steps for the five indicators and recorded the data in a table.
