Hi, in this question we are having three parts.
00:03
In the first part of the question we are given that concentration of hno3 is equal to 5 molar.
00:10
It means the concentration of hydronium ion that is h3o plus ion is also equal to 5 molar.
00:16
We are asked to calculate the ph of solution.
00:19
We can say the ph is equal to minus log hydronium ion concentration.
00:25
We can substitute the given value here in this manner.
00:30
Now on solving this we are getting the ph of solution is equal to minus 0 .70.
00:36
Now in second part we are given with this equilibrium reaction and we are asked to predict whether the equilibrium lies to the left or to the right.
00:45
We can see ammonium ion reacts with hydroxide ion to produce ammonia and water.
00:51
We can say ammonium ion is stronger acid than h2o.
01:03
Therefore we can say that equilibrium favors the weaker side.
01:17
Hence we can say that equilibrium will shift towards the right.
01:31
This is the answer of second part...
