Question

K Consider the following data on some weak acids and weak bases: adid base name formula name formula hypochlorous add HCIO |3.0 x 10-8 Pyridine CHN 1.7*10-9 acetic add HCH,CO2 1.8 * 10-5 ethylamine C, H, NH2 6.4 x 10-4 Use this data to rank the following solutions in order of increasing pH. In other words, select a 'l' next to the solution that to the solution that will have the next lowest pH, and so on. solution 0.1 M NaCH3CO2 CHOOSE 1 (lowest) 0.1 MKCIO 0.1 M Na 4 (highest) 0.1 M gia NHỚ I Don't Know

Answer 1

Answer:-

0.1 M NaCH₃CO₂  = 3

0.1 M KClO = 4(highest)

0.1 M NaI = 2

0.1 M C₅H₅NHCl = 1

The pH of the salt depends upon the Ka value of acid and Kb value.

If the Ka value is small then its salt solution will have hight pH and if the value Kb is small its salt solution will have lower pH.
