Assuming the pure water has a pH of 7, the concentration of hydrogen ions is of 10-7 mol/L. The concentration of hydrogen is equal to 10pH mol/L in water where no reaction is occurring

To get the exact number of molecules in one liter of water, multiply the number of moles by the Avogadro number (approximately 6,022x1023)

10 ^ -7

The answer is 10 to the negative 7. For the most part, water's pH is always 7 (except for rain water which is slightly more acidic with a pH varying from 5-6).

Yes, there are 1.0*10-7 mol/L H+ ions in pure water of 250C; that's why pH = 7

( = -log[H+] = -log[1.0*10-7] )

The is no H^- in pure water, so the concentration would be zero. If you meant the concentration of H^+, then at 25ºC it would be 1x10^-7 M.

Does Pure water have more H ions than OH- ions?

Yes. The concentration of H+ and OH- ions is the same.


Does acidic solutions contain higher concentration of H ions than pure water?

Yes, it does.


What is the greatest concentration of water?

1) Pure water, because it contains no concentration-diminishing impurities; 2) As to the pH of pure H2O: Pure water has what is known as a disassociation constant. H2O = H2O & H+ (aq) & OH- (aq); to quite a small degree {pure} water is a weak acid; 3) In fresh water lakes.

If your question is what is the pH of pure water, then the answer is seven, which means water is neutral.


Is the concentration of water molecules higher in pure water or in sugar water?

Concentration of water molecules is higher in pure water


What would be the pH of the solutions that have H plus ions greater than pure water?

Pure water is neutral - pH 7 If a solution has a high concentration of H+ ions it is acidic and will have a pH between 0 and 6.9 depending on the strength of the acid.


What is the product of H3O plus and OH- concentrations in water?

The concentration of hydronium ions in pure water can be thought of as the concentration of H+ ions in water. Since the pH of pure water is 7 and pH is -log(concentration of H+ ions). This means that there are 10^-7 M of H3O+ ions in pure water.


Is lower concentrations of H ions than pure water?

The concentration of hydrogen ions determines the pH. Since water is neutral with a pH of 7 or so, any substance with a lower concentration is acidic.


Concentration of water in pure water?

The concentration of pure water is 55 molar. In other words, 1 liter of water holds 55 moles of H2O


Is a solution of Ph7 neutral?

Yes. Pure water contains both H+aq and OH- in equal amounts at a concentration that corresponds to a pH7


How conductivity of water related with concentration?

pure water is insulator.


What is the pOH of pure water at 60C?

pH = -log(concentration of H+ ion) which indicates acid pOH = -log(concentration of OH- ion) which indicates base In pure water at 25 degree Celsius, concentration of H+ and OH- is equal i.e. 10^-7 mol/dm^3 so, the sum of pH and pOH is -log(10^-7) + -log(10^-7) = 7 + 7 = 14
