ment Assignment Booklet B1 22. After a rainstorm, the pH of water in a river is slightly lowered because rainwater contains dissolved carbonic acid. The concentration of hydronium ions, [H,Oi) in the rainwater is less than the concentration of carbonic acid, (H,CO), in the rainwater because is a (H,COl A. strong acid and does not completely dissociate B. weak acid and does not completely dissociate C. strong acid and completely dissociates D. weak acid and completely dissociates When fermentable carbohydrates are left in the mouth, bacteria in the mouth produce an acid with a pH of 5.200. This acid can lead to tooth decay. The hydronium ion concentration, [H,O), of this acid is a.be x 10 mol/L. 23. b Use the following information to answer question 24. A Reaction That Occurs in Albertan Lakes CO+ H,O - H,O + HCO A lake on eastern Baffin Island has a pH of 6.25. If the pH indicator thymol blue is added to a sample of water from the lake, then the colour of the resulting solution will be 24. - A. red B. blue C. orange D. yellow 25. The pH of a particular lake water sample changes from 6.6 to 4.6 downstream, which means that the hydronium ion concentration, (H.O), increases A. 0.1 times B. 1.0 times C. 10 times D. 100 times ADLC I Science 30
