Answer : The pH of the solution is, 3.41
Explanation :
First we have to calculate the moles of .
Now we have to calculate the value of .
The expression used for the calculation of is,
Now put the value of in this expression, we get:
The reaction will be:
Initial moles 0.375 0.100 0.375
At eqm. (0.375-0.100) 0 (0.375+0.100)
= 0.275 = 0.475
Now we have to calculate the pH of solution.
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
Thus, the pH of the solution is, 3.41
Answer:
<h2>3 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
