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.)
It is NOT greater. It is smaller. This is because the Hydrogen ion has lost its electron from the atom and is thus smaller. The hydrogen ion is a proton.
A hydrogen ion concentration of 110? 110 what? Or is that supposed to be 1x101
Acids increase the hydrogen ion concentration in a solution.
The pH value of a particular solution is equivalent to -log[hydrogen ion concentration].
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.
Acidic
The pH of a solution measures the hydrogen ion concentration in that solution. A small change in pH represents a large change in hydrogen ion concentration. For example, the hydrogen ion concentration of lemon juice (pH of 2.3) is 63 times greater than that of tomato juice (pH of 4.1), and 50,000 times greater than that of water (pH of 7.0). mustki2005@yahoo.comNigerian
greater the concentration of H+ ions, greater is the acidity
It is NOT greater. It is smaller. This is because the Hydrogen ion has lost its electron from the atom and is thus smaller. The hydrogen ion is a proton.
A solution with a greater concentration of hydrogen ion (H+) than hydroxide ion (OH-) is an acid while the inverse would be a base.
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.
100 times
Any (Strong) acid with a hydrogen ion concentration of 1mol/L. If an acid has a greater concentration, the PH is negative.
A hydrogen ion concentration of 110? 110 what? Or is that supposed to be 1x101
None. In a solution with a pH of 7 the hydrogen ion concentration is equal to the hydroxide ion concentration.
A chemoreceptor can detect changes in hydrogen ion concentration.
A measurement of hydrogen ion concentration is pH, which equals-log[H+], which is the negative logarithm of the hydrogen ion concentration (actually activity, but that is usually ignored). This quantity can be measured with a hydrogen electrode (as found in a pH meter), which is a type of ion selective electrode.
