What is the pH of solutions?
The pH can be calculated as:
[tex]\rm pH=-log [H^+][/tex]
The pH of the following solutions is given as;
- Oven cleaner
[tex]\rm [H^+]=10^{-13}[/tex]
The pH of the oven cleaner is:
[tex]\rm pH =-log[10^{-13}]\\pH=13[/tex]
The pH of the oven cleaner is 13.
- Water
[tex]\rm [H^+]=0.0000007[/tex]
The pH of a water sample is:
[tex]\rm pH=-log \;[0.0000007]\\pH=6.15[/tex]
The pH of the water sample is 6.15.
- Blood
[tex]\rm [H^+]=0.00000004[/tex]
The pH of the blood sample is:
[tex]\rm pH=-log\;[0.00000004]\\pH=7.39[/tex]
The pH of the blood sample is 7.39.
- Vinegar
[tex]\rm [H^+]=0.0063[/tex]
The pH of the vinegar is :
[tex]\rm pH=-log\;[0.0063]\\pH=2.20[/tex]
The pH of the vinegar sample is 2.20.
