Concentration of hydrogen ions in solution is called?
Concentration of hydrogen ions in a solution is called: Acid concentration and pH = - log10(hydrogen ions concentration, in mol/l)
Is the pH of solution is the negative logarithm of its hydroxide ion concentration?
No, the pH is the negative logarithim to base 10 of the Hydrogen Ion concentration.
What is the pH of a solution in which the concentration of hydrogen ion is greater than the concentration of hydroxide ion?
Acidic
Ph value of sodium hydrogen carbonate?
Alkaline, but you need to know the concentration and the dissociation constant to calculate pH
What is the pH of 3 percent hydrogen peroxide and water solution?
Since the dissociation constant for hydrogen peroxide is 2.4 x 10^-12 (very very small) if only a 3% concentration were to be mixed with water the pH would be negligible. However the main reason Hydrogen peroxide stings when you spill or pour it on a cut to disinfect it is because of its fairly high reactivity.
Does a pH of 3 have a greater hydrogen ion concentration than a 9 pH?
pH come from "pondus hydrogenii" or "potential hydrogen." It measures the concentration of hydrogen ions. Mathematically, pH = -log[H+] Therefore, to answer your question, a pH of 3 will have a 10-3M of hydrogen ions where as the pH 9 solution will have a 10-9M of hydrogen ions. The lower the pH the higher its H+ concentration and the more acidic it is. (A pH of 9 is actually basic.)
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.
What solution has a greater concentration of hydrogen ions a pH of 7 or a pH of 3?
When the pH is low, the concentration of the hydrogen ions is high. So pH of 3 has a greater concentration of hydrogen ions.
What is the pH of a solution that has a concentration of hydrochloric acid equal to 0.001 M?
Remembwer pH is = the negative logarithm to base ten, of the hydrogen ion concentration . So with a concentration of 0.001 M The hydrogen ion concentration is 0.001 = 10^(-3) ph = -log(10)[H^+] pH = -log(10)10^-3 pH = -(-3) log(10)10 ( Remember log(10)10 = 1 ) pH = -(-3)(1) = --3 = 3 pH = 3
Why you need pH?
pH is used as a measurement of the concentration of hydrogen ions in a solution. pH is the negative logarithm of the hydrogen ion concentration.
What is the pH of a hydrogen solution that has a hydrogen concentration of 10-2?
If concentration of Hydrogen in solution is 10-2 then its pH must be 2.
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 is the pH of soultion?
PH means negative logarithom of hydrogen ion concentration…so value of hydrogen ion concentration in solution is called the PH of solution.
Does a pH of 3 have more hydrogen than a pH of 7?
Yes. The Lower the pH (not PH), the greater concentration of H+ ions present in the solution.
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
What scale measures the concentration of hydrogen ions?
The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale
What element are you measuring the concentration of ions of when measuring the pH of a substance?
You are measuring the concentration of the cation of hydrogen. Hence the name 'power of Hydrogen' -> pH
