A numerically high pH , the hydrogen ions are very low . e,.g, pH 12 is a very alkaline solution.
A numerically low pH , the hydrogen ions are very high . e.h. pH 2 is very acidic .
What else can I help you with?
Is it true that An acidic solution has a very high concentration of OH ions?
No it is false -it has a high concentration of H+ ions
Is it true the lower the pH the higher the hydrogen ion concentration?
Yes, that is true. A lower pH indicates a higher concentration of hydrogen ions in a solution, while a higher pH indicates a lower concentration of hydrogen ions. pH is a measure of the acidity or basicity of a solution on a scale from 0 to 14.
What is true of the hydroxide and hydrogen ions in a solution of pH 7?
In a solution with pH 7, the concentration of hydroxide ions (OH-) equals the concentration of hydrogen ions (H+), with each being 10^-7 moles per liter. This represents a neutral solution where the two ions balance each other out.
Is it true that in strong acids most of the molecules break up into ions in the solution?
Yes, that is true. Strong acids ionize, in a aqueous solution. It is the released hydrogen ions that make them acids.
Is it true the lower the pH means the greater number of hydrogen ions?
Yes, that is correct. A lower pH indicates a higher concentration of hydrogen ions in a solution, which means it is more acidic. pH is a measure of the concentration of hydrogen ions in a solution on a logarithmic scale.
Is it true that An acidic solution has a very high concentration of OH ions?
No it is false -it has a high concentration of H+ ions
The concentration of hydrogen ions in solution is the pH of the solution the answer has to be either true or false?
True. The concentration of hydrogen ions in a solution directly determines the pH of the solution. A lower concentration of hydrogen ions results in a higher pH, while a higher concentration of hydrogen ions results in a lower pH.
Is it true that The pH scale measures the concentration of hydroxide ions?
No, pH measures the concentration of hydrogen ions. pOH would measure hydroxide concentration.
Is it true the lower the pH the higher the hydrogen ion concentration?
Yes, that is true. A lower pH indicates a higher concentration of hydrogen ions in a solution, while a higher pH indicates a lower concentration of hydrogen ions. pH is a measure of the acidity or basicity of a solution on a scale from 0 to 14.
What does the pH scale measure the concentration of?
The pH scale is a Science indicator, Not a Mathmatical one :-)

What pH indicates that the most hydroxide ions are present?
The highest pH value in a group of such values indicates that the greatest concentration of hydroxide ions is present in the substance with the highest pH. This is true because a higher pH indicates a lower concentration of hydrogen ions, and the product of the molar concentrations of hydrogen and hydroxide ions must always be 10-14 at standard temperature and pressure in a mixture that is mostly water.
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 is true of a Arrhenius acid?
An Arrhenius acid donates H+ ions
Is an acid is any compound that forms H plus ions in solution true?
Not all the time. Only acids that react with metals will give of Hydrogen (H) Acid + Metal --> Salt + Hydrogen
