Question
H. pH and capacity of buffer dependence on the ratio of total concentration (IA)+[HA)) Take5.0 mL of solution 2 and dilute it to 50 mL by addition of water to make solution e. f. Take 10.0 mL of solution 4 and repeat procedure in Part 8 Take0.5 mL of solution 2 and dilute it to 50 mL by addition of water to make solution h. Take 10.0 mL of solution 4 and repeat procedure 's' in Part E Volume (mt) ofvolume (mL) of solution HsPO4 (1 M) 10 25 40 NaHaPO (1M] 40 25 10 pH pH pH after 5 drop pH after pH after pH after solution calculatedme 2.06 2.48 5.88 asured HCI 1.83 2.07 2.2B 10 drop HCI 1.71 2.05 1.58 5 drop NaOH 1.96 2.69 .93 10 drop NaOH 3.36 5.46 11.58 What is the pH calculated of solution 2,4,5 Words E English (US) 252Explanation / Answer
In solution 2 after 5 drops and 10 drops of HCl pH is 1.71 and with further addition of another solution of NaOH 5 drops and 10 drops pH become 3.36
Therefore,pH calculated for solution 2 = 3.36-1.71 = 1.65
In solution 4 after 5 drops and 10 drops of HCl pH is 2.05 and with further addition of another solution of NaOH 5 drops and 10 drops pH become 5.46
Therefore,pH calculated for solution 4 = 5.46-2.05 = 3.41
In solution 5 after 5 drops and 10 drops of HCl pH is 1.58 and with further addition of another solution of NaOH 5 drops and 10 drops pH become 11.58
Therefore,pH calculated for solution 5= 11.58-1.58 = 10.0
