What happens to the Ph when acids release hydrogen ions in water?
it decreases
If pH decreases by 1 pH number on the scale then how much has the concentration of hydrogen ions increased by?
the hydrogen ion conc=0.1
What solute dissociates to release hydrogen ions and cause decreases in pH?
Acid
If pH increases does a group become more or less protonated?
If pH increases, then the solution is less protonated. The pH of a solution is defined as -log[H+], so when the concentration of hydrogen ions increases, the pH decreases.
Why the acidic character increases with the decrease in pH?
The acidic character increases with decrease in pH because the pH and acidity are both dependent on the hydrogen ion concentration, with pH being the negative log of the hydrogen concentration. So, at the concentration of H+ increases, the negative log of the H+ concentration decreases.

What happens to the hydrogen ion concentration as you decrease the pH?
Hydrogen ion concentration increases.
Is there a two-folded increase in hydrogen for every pH unit as the scale decreases?
ten-folded
What is A measurement system used to indicate the concentration of Hydrogen ions in solution?
the pH scale. as the pH of the solution decreases (below 7), the concentration of H+ ions increases. as the pH of the solution increases (above 7), the concentration of H+ ions decreases. (if the pH is 7, the solution is neutral).

What makes pH go up and down?
pH tells us the hydrogen ion (H+) ion concentration. The lower the number - the greater the number of hydrogen ions. Adding hydrogen ions decreases pH (and increases acidity) removing them (eg by adding hydroxide OH-) increases pH.
What is the relationship between the pH and in hydrogen ion concentration?
pH = -log[H+].Hence lower the pH, higher is the concentration of H+ ions.For exampleAt pH = 1, [H+] = 0.1 MAt pH = 2, [H+] = 0.01 MAt pH = 3, [H+] = 0.001 Mand so on...
What happens to the hydrogen ion when the PH increases?
the pH level decreases or becomes more acidic
How does CO2 decrease the pH?
Adding water does not always decrease pH. pH is a measure of the concentration of hydrogen ions, also called hydronium ions. They are inversely related. More hydrogen ions means a lower pH. A base has a pH greater than 7 (neutral) because it has an increased amount of hydroxide ions which causes a lower amount of hydrogen ions. Adding more water to a base solution causes the concentration of the hydroxide ions to become less, thus due to equilibrium, causing the hydrogen ion concentration to increase. This does cause pH to become less ... decrease. But an acid solution does the exact opposite when water is added. It already has a large concentration of hydrogen ions, but as water is added the concentration decreases and this causes pH to increase.
