What Is The Ph Of A 1.2 M Ch3nh3no3 Solution
What is the pH value of 0.015 M solution of CH3NH3NO3? Kb (CH3NH2) = 5.2 x 104? 3
What is the pH value of 0.015 M solution of CH3NH3NO3?
Kb (CH3NH2) = 5.2 x 104?
The answer is 6.27, but w?
CH3NH3NO3
CH3NH2NO3> CH3NH3 + + NO3
CH3NH3 + CH3NH2 + H +
KB of (CH3NH2) = 5.2 x 104
CH3NH2 + H2O CH3NH3 + + OH
Kb = [CH3NH3 +] / [CH3NH2]
1 / Kb = [CH3NH2] / [CH3NH3 +]
Use 1 / (5.2 x 10 4) = x / (0.015 x) 5% arbitration
x = 7.8 x 10 6 = [OH]
PH = 5.108
Well, I tried the same answer and found a solution.
Since CH3NH3NO3 is an acid, change to 5.2 x 104.
Divide by 1.0 x 1014 to get ka. Get
Then use simple calculations and multiply ka by 0.015 M and then by the square root.
This will be your x and you will get logx to find your answer.
This is 6.269956, this is 6.27.
