Verified answer
The pH scale works like this:
1 being acidic, like lemon juice,
10 is basic, amonia
the lower the number the more acidic, higher numbers are basic and 7 is neutral
the stronger the base, the higher the number, which means a higher OH ion concentration. the stronger the acid, the lower the number, means a higher H3O ion concentration and a lower OH concentration.

Does a pH value signify certain number of hydrogen or hydroxide ions?
"pH" is a convention used as a convenience. It indicates how acidic (or basic, that is, alkaline) a solution is. It is the negative logarithm of the hydrogen ion concentration, usually the latter is expressed in moles (or millimoles) per liter. Moles per liter is, of course, what we call "molarity." pOH is used in the same way, indicating the concentration of hydroxyl ions. Generally, Concentration of hydrogen ions + the concentration of hydroxyl ions = 10-14 A neutral solution has equal numbers of H+ and OH-
What is the accepted Ka value for sodium hydroxide?
NaOH does not have a Ka because it is not an acid. Ka is the concentration of the acid, therefore non valid. It can have a Kb though. Hope this helps
What is hydroxide ion concentration if pH 8?
To find the hydronium ion concentration from pH, set base 10 to the negative power of the pH. Here that corresponds to 10 to the power of -8.75 The answer is 0.000000002 or 2x10^-9 Although this response is correct in saying that concentration and pH are based on sets of base 10; however, it is incorrect in it's response. From pH--> [H30] -log(pH) From [H30]---> pH 10^(-pH)
What is the pH value of ammonium hydroxide solution?
It depends on the molarity of the solution
What is potassium hydroxide or sodium hydroxide?
What do you want to know about it? Potassium hydroxide will dissolve in water to form a solution containing disassociated Ka+ and OH- ions. Potassium hydroxide is a strong alkali. Potassium hydroxide has the chemical formula KOH.
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 has the highest pH value acetic acid or sodium hydroxide or sodium carbonate or sulphuric acid?
sodium hydroxide
What has the highest pH value dilute sodium bicarbonate or lemon juice or dilute sodium hydroxide solution?
dilute sodium hydroxide solution
What is the range of pH in acid and how this is linked to the concentration of acid?
in pH acids range from 0-6.as the highest value is 6 and if the concentration of an acid is 6 it is concentrated as this value drops the concentration drops
What concentration indicates a basic solution?
I think you mean the pH value, it so, a basic solution has any value exceeding 7.
When H2O dissociates into what pH value indicates that the concentration of H equals OH?
The neutral pH is 7,00.
What is the pH scale of Barium hydroxide?
pH depends on concentration. However, the best way to compare bases (and acids) is to use the pKb value; the pKb of barium hydroxide is around -2, which makes it extremely basic.
What effect would it have on the value of the concentration of sodium hydroxide if the conical flask contains some distilled water before the addition of potassium hydrogenphthalate?
the conentration will be increased.

What contributes to different pH levels?
pH indicates the ionisation value in a solution and generally stated negative logarithmic value of H ion concentration. for example, if you add hydrochloric acid to water, the solution is fully ionised and H ions and chlorine ions are freely in the solution. the strength of H ions in the solution indicate the pH value. Lower the pH value, higher is the H ion concentration since the pH number is derived from negative log of h ion concentration. Similarly, the OH ion concentration indicate a base as against a H ion concentration indicating acid. When the pH is above 7, it indicates that the solution is alkaline.
Strongest base a pH can have?
Practically pH of 14 or 15 is the highest base value reachable, due to limits of max. concentration.
