The meaning of HYDROGEN-ION CONCENTRATION is the concentration of hydrogen ions in a solution expressed usually in moles per liter or in pH units and used as a measure of the acidity of the solution. How to use hydrogen-ion concentration in a sentence.
Noun1.hydrogen ion concentration- the number of moles of hydrogen ions per cubic decimeter concentration- the strength of a solution; number of molecules of a substance in a given volume pH,pH scale- (from potential of Hydrogen) the logarithm of the reciprocal of hydrogen-ion concentration in ...
Chemistry Chapter Acids and Bases. (Self-Ionization of Water) H 2 O + H 2 O H 3 O + + OH - Two water molecules collide to form Hydronium and. PH And pOH. Water Water autoionizes H 2 O + H 2 O H 3 O+ + OH- Hydrogen ion concentration determines the acidity of th...
They indicate further that concentrations of hydrogen ions which are unfavorable for the growth of didinia do not facilitate encystment and, in general, that changes in hydrogen-ion concentration are of little importance in inducing encystment in Didinium....
pH Scale:A pH meter measures the acidity of a solution. The value that the pH meter gives ranges from 1-14. When we know the pH of a solution, we can characterize the solution as acidic, basic or neutral. In reality, the pH meter measures the activity of the protons present in...
What is the pH if the hydrogen-ion concentration is 6.8×10−7 M? pH: The pH scale is a dimensionless logarithmic scale that allows one to determine whether a solution is acidic or basic. Basically, the pH scales ranges between 0 and 14. Any pH value that falls within 0...
What is the hydroxide ion concentration if the given pH is 11? Show your solution. If the pH of a solution is 10, what is the hydronium ion concentration? What is the hydrogen ion [H^+] concentration of a solution of pH 8? How many hydroxide ions are present in a solution th...
Typically, the pH that is less than 7 pertains to an acidic solution, while a pH that is greater than 7 pertains to an alkaline solution. Answer and Explanation: We determine the concentration of hydrogen ions, {eq}\displaystyle [H^+] {/eq}, in th...
pH n (Chemistry) potential of hydrogen; a measure of the acidity or alkalinity of a solution equal to the common logarithm of the reciprocal of the concentration of hydrogen ions in moles per cubic decimetre of solution. Pure water has a pH of 7, acid solutions have a pH less than 7, ...
