Elements are used to create bonds and are classified as particles.
The pH scale for acids and bases ranges from 1 - 14. The answer is letter C. The rest of the choices do not answered the question above. There are quite a few
relationships between [H+] and [OH−]
ions. And because there is a large range of number between 10 to 10-15
M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, [H+
][OH- ] = 10-14. From here we can derive the values of each concentration.
-log[H+ ] + -log[OH- ] = -log[10-14]
pH + pOH = 14
So pH = 14 – pOH and pOH = 14 –
pH
Answer:
0.2M
Explanation:
Data obtained from the question include:
C1 = 2.0 M
V1 = 100mL
V2 = 1000mL
C2 =?
Using the dilution formula C1V1 = C2V2, the molarity of the diluted solution can be obtained as follows:
C1V1 = C2V2
2 x 100 = C2 x 1000
Divide both side by the 1000
C2 = (2 x 100) / 1000
C2 = 0.2M
The molarity of the diluted solution is 0.2M
