How is a change in hydrogen ion concentration reflected in the pH?
pH is the negative logarithm of the hydrogen ion concentration; so an increase in hydrogen ion concentration give a reduction in pH. A reduction in hydrogen ion concentration causes an increase in pH.
As hydroxide ion concentration increases the Ph will increase or decrase?
As hydroxide concentration increases pH increases
What would happen when Excess of calcium hydroxide in acidic soil?
PH increase
What does an increase 1 pH number represent?
A decrease in hydrogen ion concentration by factor of 10
What does an increase of 1 pH number represent?
10x increase in acidity
How do we convert dichromate ion into chromate ion?
The conversion increase when the pH increase.

How do you convert dichromate ion into chromate ion?
Conversion is increased when the pH increase.

As hydroxide concentration increases pH increases
Which materials could be increase the pH of soil or compost?
Lime.
How does temperature affect pH levels in soil?
This is quite simple. Temperature affects the pH levels in soil because of the heat. Depending on the intensity, the pH level in the soil will either increase or decrease to balance.
How will soil pH change as you go further away from a lake?
The pH of soil will change as you move further away from a lake due to the increase of nutrients found in soil.
What does an increase pH of 1 represent?
A decrease in hydrogen ion concentration by factor of 10
How does high hydroxide ion concentration do to a solution?
In this case the pH increase over 7.
How does the concentration of hydrogen ions vary with pH?
pH is the negative log of the hydrogen ion concentration. So lowering pH from 5 to 4 means a ten times increase in hydrogen ion concentration. Increasing pH by 1 results in decreasing hydrogen ion concentration to 1/10th its former level.
What would happen when Excess of calcium hydroxide in acidic soil?
PH increase
Why is limestone used as a agricultural product?
To increase the pH level in the soil so that the soil does not become too acidic.
