Express the pH of the solution ot three decimal places. 20.00 mL of 1.20 M HCl diluted to 0.570 L

Consider the following data on some weak acids and weak bases: formula hydrocyanic acid HCN hypochlorous acid HCIO name acid 01 M Nacio 0.1 MC₂NHBr 0.1 KBr 0.1 MKCN solution 49 10 10 3.0 10 Use this data to rank the following solutions in order of increasing pH. In other words, select a 'I' next to the solution that will have the lowest pH, a 2 next to the solution that will have the next lowest pH, and so on. PH choose one 8 choose one choose one 8 those base 3 K₂ formula pyridine CHN 17-10 ammonia NH, 18×105 name 腰国语。

10. Which solution would be expected to have the highest pH? (No calculation needed.) A. 0.50 M NaOH B. 0.05 M HC1 C. 0.05 M CH3NH₂ D. 0.60 M CH3COOH

A solution is made by dissolving 15.4 g of HCl in 500 mL of water. Calculate the pHof the solution assuming the volume remains constant.
