ok. We are given the following equation:
Where:
Since we are asked to determine "H" we will solve for "H" in the equation. To do that we will first multiply both sides by -1:
Now, we will use the following property of logarithms:
Applying the property and having into account that:
We get:
Now we substitute the given value of "pH = 4.5":
Solving the operation:
Therefore, the hydrogen ion concentration of the fluid is 0.000032
K, so areitmetic
an=a1+d(n-1)
a1=first term
d=common differnce
we are given
a1=2 and 3/4
6th term is 3 and 7/12
so
a6=3 and 7/12=2 and 3/4+d(6-1)
3 and 7/12=2 and 3/4+d(5)
minus 2 and 3/4 both sides
10/12=5d
divide both sides by 5 or multiply both sides by 1/5
2/12=d
1/6=d
or
that is the rule
an=a1+d(n-1)
a1=first term
d=common differnce
we are given
a1=2 and 3/4
6th term is 3 and 7/12
so
a6=3 and 7/12=2 and 3/4+d(6-1)
3 and 7/12=2 and 3/4+d(5)
minus 2 and 3/4 both sides
10/12=5d
divide both sides by 5 or multiply both sides by 1/5
2/12=d
1/6=d
that is the rule
