The hydrogen ion concentration of a
solution is 0.001moles/liter. What is
the pH of the solution?
Answers
Answer:
If the hydrogen ion concentration is 0.00000001 moles per liter, this would be a solution with a pH of 8, which would be a basic solution. Here is how this was determined:
By definition, using [H+] to represent the concentration of the hydrogen ions in moles per liter,
p
H
=
−
l
o
g
10
[
H
+
]
If we take the equation for pH and fill it in with the H+ concentration, we can then calculate the pH:
p
H
=
−
l
o
g
10
[
H
+
]
p
H
=
−
l
o
g
10
0.00000001
p
H
=
8
Thus, the pH would be 8. Examples of solutions with pH 8 would be seawater or baking soda solution. A solution with pH 8 is a base since the pH is above 7. Solutions with pH exactly 7 would be neutral, and those with a pH below 7 would be acidic, and those with a pH above 7 would be basic.
Let's take a look at another example. Let's say that the hydrogen ion concentration of a solution was 0.001 moles per liter. What would the pH be for that solution? We can use the same equation, just filling in the hydrogen ion concentration with 0.001:
p
H
=
−
l
o
g
10
[
H
+
]
p
H
=
−
l
o
g
10
0.001
p
H
=
3
This would be a very acidic solution, similar to what we might find in a carbonated beverage or in the gastric juices in our stomach.
Explanation:
Answer:
The pH of the given solution is 3.
Explanation:
Given that,
The hydrogen ion concentration of a solution is
And we are required to find the pH of the solution.
The pHof a solution is the negative logarithm of hydrogen ion concentration of the solution.
It can be mathematically written as
Substituting the given value in the above relation we get
Therefore,
The pH of the given solution is 3.
