If PH is 7.5 what is the value of H?
From the abbreviation of "power of Hydrogen" pH is the negative, base ten logarithm of the hydronium ion (H3O+) concentration in a solution. The concentration of the hydronium ion in a solution that has a pH of 7.5 is 1 x 10-7.5 Molar (moles per liter).
Describe a solution with a pH of 9?
This solution is basic, since it has very little dissolved Hydronium ion. (It has exactly 10-9 hydronium ions per Liter, which is very few. Less hydronium ions means less acidity.) Remember too that a solution with pH > 7 is basic, and a pH < 7 is acidic. Remember that pH is a number that represents the concentration of hydronium ion (H+) in a solution. The equation for this is pH = -log10[H+]. If you have a pH of 9, then you can solve for the concentration of hydronium ions as follows. pH = 9 -9 = log10[H+] You can then raise both sides of the equation to the power of 10 in order to eliminate the log. 10-9=10log10[H+] 10-9=[H+] since 10log10[H+] = [H+] So a pH of 9 indicates a hydronium ion concentration of [H+] = 10-9
What is meant by the pH of a solution?
The value for pH (classically 0 to 14) is the measure of how acidic or basic a solution is.The abbreviation is from the term power or potential of hydrogen, giving the relative molar concentration of hydronium ions (H3O+ i.e. hydrogen ions in solution).
What is pH for?
Many substances have a place in the pH scale. a pH is measured from 0 (The most acidic) to 14 (The most basic). Water, for example, has a pH of 7 (Neutral). Hydrocloric acid has a pH of 0 and drain cleaners have a pH of 14. Both are very corrosive and should never be in contact of your skin.
Why the PH scale has no unit?
pH has no unit because it's a it's a logarithmic scale, not a measurement like grams or degrees. The pH number directly relates mathematically to the actual concentrations in solution. Concentration itself does have units, but pH really only looks at the power (or exponent) of the concentrations. And, for that reason the unit doesn't carry. For example: pH = - log [H30+] (mathematical definition) = negative logarithm of the hydronium ion concentration. What this means is that if a solution has a concentration of 10-7 M [H30+] or (0.0000001 moles per litre of the hydronium ion), the negative log of this number = 7. Therefore the pH = 7. But it's not 7 moles per litre or 7 moles or any other transferable unit. It's just 7. Hope that helps a little.

How to measure the acidity and basicity of a substances?
The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution. The letters pH stand for power of hydrogen and numerical value for pH is just the negative of the power of 10 of the molar concentration of H+ ions.
The reason pure water is considered neutral with respect to pH is because?
The concentration of hydronium ions is one time ten to the negative seventh power, and seven on the pH scale is neutral.
Why is pure water neutral?
The concentration of hydronium ions is one time ten to the negative seventh power, and seven on the pH scale is neutral.Because it pH is close to 7. It is neither acidic nor basic

What is the concentration of hydrogen ions in a pH equals 1 solution how does it differ from a solution of pH equals 2?
Remember: by definition the concentration of hydrogen ions (in mol/L) is equal to 10 to the negative power of the pH value (pH).[H+] = 10-(pH)Using this we find that: [H+] = 10-1.0 = 0.1 for pH = 1.0 and[H+] = 10-2.0 = 0.01 for pH = 2.0 , thus 10x smaller!

What does phs stand for?
Some say that pH stands for the "power of hydronium," (or hydrogen) but this is disputed. Other interpretations include "percentage of hydronium" or "potential of hydronium," with hydronium interchangable with "hydrogen." The "p" could also be a constant that means "the negative log of" as in pKa.
