A solution of HCl has a concentration of 1.20 x 10-2 M. What is the pH of this solution?
2 answers:
<u>Answer: </u> The pH of the solution is 1.92
<u>Explanation: </u>
To calculate the pH of the solution, we use the equation:
We are given:
Hydrochloric acid is a monoprotic acid and it dissociates 1 mole of hydrogen ions. So, the concentration of hydrogen ions is
Putting values in above equation, we get:
Hence, the pH of the solution is 1.92
-log (1.2x10^-2) = 1.92 so C

Given that:-
The speed of light =
The distance =
The conversion of distance in km to distance into m is shown below as:-
1 km = 1000 m
So,
Distance =
The relation between speed distance and time is shown below as:-
Thus,
Time = 2633.33 seconds
Also, 1 s = 1/60 min
So,
Time=
