When the concentration of hydrogen ions increases the pH number of a solution?
When the concentration of hydrogen ions increases, the pH number of a solution decreases. pH is a measure of the acidity or basicity of a solution, with lower pH values indicating higher acidity.
Does the pH scale indicate the consentration of hydrogen ions or hydroxide ions?
The pH scale indicates the concentration of hydrogen ions in a solution. A lower pH value indicates a higher concentration of hydrogen ions, while a higher pH value indicates a lower concentration of hydrogen ions.
When the pH is high the concentration of hydrogen ions is low?
Yes, that's correct. pH is a measure of the concentration of hydrogen ions in a solution. When the pH is high, it means there are more hydroxide ions present relative to hydrogen ions, indicating a lower concentration of hydrogen ions.
When the pH is high what is true about the concentration of hydrogen ions?
When the pH is high, the concentration of hydrogen ions is low. This is because pH is the negative logarithm of the hydrogen ion concentration, so a higher pH value corresponds to a lower concentration of hydrogen ions.
Why do the levels of pH decrease when the level of H increases?
When the level of H+ ions increases in a solution, it leads to a higher concentration of hydrogen ions. This increase in hydrogen ions lowers the pH of the solution because pH is a measure of the concentration of hydrogen ions in a solution. The pH scale is inversely related to the concentration of hydrogen ions, so as the concentration of H+ ions increases, the pH decreases.

How does the phosphate buffer system help in maintaining the pH of our body?
The phosphate buffer system consists of two ions: dihydrogen phosphate ions and hydrogen phosphate ions. When the number of hydrogen ions in a body's bloodstream increases (pH drops), hydrogen phosphate ions accept hydrogen ions in order to maintain the equilibrium between the concentration of hydrogen and hydroxide ions within the bloodstream. When the number of hydrogen ions in the bloodstream decreases (pH increases), the resulting dihydrogen phosphate ions release hydrogen ions in order to increase the number of hydrogen ions in the blood.
What is it when The number of moles of hydrogen ions equals the number of moles of hydroxide ions?
A neutral solution of about 7 pH.
What does a pH level measure?
It measures the number of hydrogen ions in a substance.
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.
How is the pH scale shifted by the use of hydrogens ions?
pH is a measure of Hydrogen concentration pH = -log10[H+], where [H+] is the concentration of hydrogen ions. From this equation, we can see that an increase of hydrogen ions will lower the pH, and a decrease of hydrogen ions will raise the pH. =D
When the pH is high the concentration of hydrogen ions is low?
Yes, that's correct. pH is a measure of the concentration of hydrogen ions in a solution. When the pH is high, it means there are more hydroxide ions present relative to hydrogen ions, indicating a lower concentration of hydrogen ions.
If pH decreases by 1 pH number on the scale then how much has the concentration of hydrogen ions increased by?
If pH decreases by 1 unit on the pH scale, it means the concentration of hydrogen ions has increased by a factor of 10. For example, if the original pH was 7 and it decreases to 6, then the concentration of hydrogen ions has increased by 10 times.
When the pH is high what is true about the concentration of hydrogen ions?
When the pH is high, the concentration of hydrogen ions is low. This is because pH is the negative logarithm of the hydrogen ion concentration, so a higher pH value corresponds to a lower concentration of hydrogen ions.
What scale measures the concentration of hydrogen ions in solution?
A measure of the concentration of hydrogen ions in solutions is the pH. Solutions with more hydrogen ions are acids, and substances with less hydrogen ions are bases. Furthermore, each number descending has ten times the amount of hydrogen ions of the previous number (ie a solution with a pH of 5 has 1,000 more hydrogen ions than a solution with a pH of 8).
What is pH pure water (neutral)?
pure water is neutral with a pH of 7
