Explanation:
The reaction equation will be as follows.
Hence, the expression for is as follows.
Let us assume that the concentration of both and
is x.
x = 0.01118034
This means that the concentration of is 0.01118034.
Since, we know that the relation between pH and concentration of hydrogen ions is as follows.
pH =
=
= 1.958
Thus, we can conclude that the pH of a 0.500 M solution of arsenic acid is 1.958.
Explanation:
The number of moles of solute present in liter of solution is defined as molarity.
Mathematically, Molarity =
Also, when number of moles are equal in a solution then the formula will be as follows.
It is given that is 8.00 M,
is 7.00 mL, and
is 0.80 M.
Hence, calculate the value of using above formula as follows.
= 70 ml
Thus, we can conclude that the volume after dilution is 70 ml.
