What is the pH of a solution of 1.0 x 10 -3 M H30?

pH is the negative log of the hydrogen ion concentrationthe hydrogen ion concentration is .001 in this instance thereforepH = -log[.001] = 3


What is the pH when the hydrogen ion concentration is 2.0 x 10-3 M?

- log(2.0 X 10 -3 M) = 2.7 pH ======


What does the term pH mean?

pH is the measure of the acidity or alkalinity pH means the power of Hydrogen. It is 'minus the decimal logarithm of the hydrogen ion activity in an aqueous solution'. The term was coined by Sørensen, it measures the alkalinity or acidity of a liquid. pH is a measure of the concentration of hydrogen ions [H+] in a solution. The concentration of the hydrogen ions is measured in Molarity (M), or moles of H+ ions per liter of solution. The pH is then expressed as the negative log (base ten) of the hydrogen ion concentration. pH = -log[H+] For example, if a solution has a hydrogen ion concentration of 4.75 x 10-5 M (or 4.75 x 10-5 moles of H+ ions per liter of solution), then the pH of the solution would be -log[4.75 x 10-5] = 4.323 pH is generally given on a scale from 0-14, with 0 being the most acidic solution (like HCl) and 14 being the most basic solution (for example, NaOH.), although extreme values may sometimes fall outside that range. Pure water has a pH of 7 because its H+ concentration is 1.0 x 10-7 M -log[1.0 x 10-7] = 7


How do you convert 10 mg to 10 ml?

You divide the mass of a substance by its density.


How much mass is in 10 cm3?

That would be (10) times (the density of the substance).

What is the difference between pH and hydrogen ion concentration?

The pH value of a particular solution is equivalent to -log[hydrogen ion concentration].


What does the hydronium ion concentration measure for a substance?

The hydronium ion concentration measures the concentration of positively charged hydronium ions (H3O+) in a substance, which is a measure of the substance's acidity. Higher hydronium ion concentrations indicate a more acidic environment, while lower concentrations represent a more basic or neutral environment.


What is the pH of a hydrogen solution that has a hydrogen concentration of 10-2?

The pH of a hydrogen solution with a concentration of 10^-2 M is 2. This is because the pH is calculated as the negative logarithm (base 10) of the hydrogen ion concentration.


What happens to the hydrogen ion concentration as you decrease the pH?

Hydrogen ion concentration increases.


What is H ion concentration of ph11?

The H+ ion concentration at pH 11 is 1 x 10-11 moles per liter.


What is meant by pH solution?

p means -log10 of a number, H is shorthand for hydrogen ion concentration. If hydrogen ion concentration is 10^-4 mols/litre, pH is 4


If the hyrdoxide ion concentartion increases what happens to the hydrogen ion concentration?

As the hydroxide ion concentration increases, the hydrogen ion concentration decreases due to the reaction between the two ions. This relationship is governed by the autoionization of water, where water molecules can act as both acids (donating H+) and bases (accepting H+).


Is the pH of solution is the negative logarithm of its hydroxide ion concentration?

No, the pH of a solution is the negative logarithm of its hydrogen ion concentration, not its hydroxide ion concentration. The formula for pH is pH = -log[H+].


If a solution has a hydrogen ion concentration of 10-5M what is its pH?

The pH of a solution is defined as -log10[H+]. Thus a solution with a hydrogen ion concentration of 10-5M has a pH of 5. [H+] = 10-5 pH = -log[H+] pH = - log [10-5] pH = 5


What does an increase pH of 1 represent?

A decrease in hydrogen ion concentration by factor of 10


What does an increase of 1 number represent?

A decrease in hydrogen ion concentration by factor of 10


What does a change in pH of one unit represent in terms of hydrogen ion concentration?

A change in pH of one unit represents a tenfold change in hydrogen ion concentration. For example, a solution with a pH of 4 has 10 times higher hydrogen ion concentration than a solution with a pH of 5.
