Part A. pH estimation and explanation There are three methods to determine pH (Table 4). For litmus strips, red litmus paper turns blue in basic solution but stays red in acidic solution, while blue litmus paper turns red in acidic solution but stays blue in basic solutions. For the liquid universal indicator and pH 1-14 test papers, compare its color with the scale provided on the package to determine pH. When using litmus strips and pH 1-14 paper, use a...

what is a good hypothesis for this lab?? I need to write one. Acid Base lab INSTRUCTIONS Acid-base indicators are used to let you know whether the solution you are working with is acidic or basic. We have many acid-base indicators available to us today, but the first indicators were made from natural compounds. The indicator that you will be making comes from purple cabbage and is simply called cabbage extract indicator. Procedure: Goggle red cabbage as an acid-base indicator....

During lab you measured the pH of common household items. Write net Bronsted equations that show the acidic or basic nature of the following substances, given the pH. For polyprotic acids, please only show one proton transfer. Remember that spectator ions are not included. (Acid,Base,Conj. Base, Conj. Acid) a) fish (trimethylamine = C3H9N) with a pH = 8.20 b) grapes (tartaric acid = H2C4H4O6) with a pH = 2.90 c) lithium hydrogensulfite, an amphiprotic species with a pH = 4.40
