The acid dissociation constant K, of hypobromous acid (HBRO) is 2.3 x 10 D. Calculate the pH of a 3.3 M solution of hypobromous acid. Round your answer to 1 decimal place. pH = %3D Continue

Consider the following data on some weak acids and weak bases: acid base Ka name formula name formula HCH3CO2 1.8 × 10 C,H;NH, 4.3 × 10 5 10 acetic acid aniline hydrofluoric acid HF 6.8 x 10 ethylamine C2H;NH2| 6.4 x 10 Use this data to rank the following solutions in order of increasing pH. In other words, select a 'l' 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. solution pH 0.1 М KF choose one 0.1 M C2H5NH3CI choose one 0.1 M NaCl choose one 0.1 M NaCH3CO2 choose one

The pH scale depends on the value of Kw. What would the pH of neutral water be if the Kw was 5.54 x10-15? IMPORTANT: When entering your answer: •Enter the number only (no units) • Do not leave any spaces Use a leading zero before the decimal when necessary Report your number to 3 decimal places (regardless of the significant figures) • Correctly round your answer to the 3rd decimal place (allowed margin of error is only ± 0.001, so always use un- rounded numbers in your calculations) Examples: 0.123 or 9.876
