The activity coefficient of h is 0.05
The ph of the solution is 2.08
To find the activity coefficient, apply the concept of ionic equilibrium
h( activity coefficient)= 1/2CZ²
C is the concentration of species
Z is the charge on individual species
<em>h= 1/2( 0.01 x1²+ 0.04x (-1)²+0.01 x1²+0.04x (-1)²)</em>
<em>h= 0.05 </em>
For the pH of the solution, apply the formula
<em>pH= -log( H⁺x0.83)</em>
<em>pH = - log(0.01x0.83)</em>
<em>= 2.08</em>

The metric prefix kilo means 1,000.
Example: A kilometer is equal to 1,000 meters.
Explanation:
It is necessary that the glassware which we use during titration needs to be clean and dry before use because otherwise the remaining reagents will get mixed up with the solutions.
As a result, this will lead to a change in analysis results.
Hence, an error will occur in the resulting values.
Also, when not cleaned properly the any other substance remaining in the glassware might react with the solution leading to a change in the solution.
In that case also, error will occur.
Answer:
Coefficients represents no of moles while subscripts represent no of atoms.
<span>P*V/T=constant
so P*V= constant*T
if T doesn't change then
P*V= constant
so 150kPa*0.8L=75kPa*xL
xL=150kPa*0.8L/75kPa=1.6L
hope it help</span>
