2. What is the pll of a0.8344 M KOH selution? Scrup Answer 3. a) What is the theeretical [J of a 0.00030 M HC1? a)Answer b) The above 0.00030 M HCI sohutics was prepared in the lalb by dilution. The pH of the solution was mensured as 4 23. Calculane the ['1 from the measured ph. c) Calculate the percent error in the measured (H'1. Setup: c)Answer: 4. What is the percent ionization for cach of the following acids? a )0.022 M HC1O; solution of pHi-3.88 Setup a)Answer b ) 0.0027 M HC10; solution of pH 4.70 Setup b)Answer 5. fill in the blanks: i) The percent of ionization upon dilution ii) The [H 1 upon dilution.

Explanation / Answer

2) [KOH]= 0.0344M

So, [OH-]= 0.0344M

[H+][OH-]=10-14

So, [H+]= 29.06* 10-14

pH= 12.53

3) a)[HCl]= 0.00030M

[H+]= 0.00030M

b) pH= 4.23

[H+]=10-4.23= 5.9*10-5

c)percentage error= (3*10-4-0.59*10-4/3*10-4) *100= 80.33%

5) i) increase

ii)decrease
