Yes, if both solutions are at 25oC then in both solutions this is valid: pH + pOH = 14.0

What does pH equal mathematically?
The negative logarithm of the molar concentration of hydronium (H3O+) ions. pH=-log[H3O+]
What pH values indicates a solution with the highest concentration of hydrogen ions pH equals 1 or pH equals 2 or Ph equals 7or pH equals 14?
pH = 14 is basic pH = 7 is neutral pH - 1 and 2 are acidic; pH = 1 is more acidic than pH = 2 Therefore a solution at pH 1 has higher concentration of H+ than at pH 14
What kind of mathematical relationship exists between conductivity and concentration?
The initial concentration affects the conductivity of a solution in a sense that the greater the initial concentration,the greater the conductivity.increase in concentration means presence of more free moving ions in the solution.but this can only occur in the initial concentration because,after the initial concentration,an increase in concentration will mean that there are now more ions present in the solution but the same volume,hence the ions wouldn't be able to move freely an in the initial concentration,hence the conductivity would then decrease since they can't move freely now.
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
What is van't hoff's factor?
Van't Hoff factor expresses how many ions and particles are formed, on average, in a solution from one formula unit of solute. It is the ratio between the actual concentration of particles produced when a substance is dissolved, and the concentration of a substance as is calculated from its mass.
What is true about the relative concentrations of hydronium and hydroxide ions in an acid solution?
In an acidic solution, the relative concentration of hydronium ions will always be higher than hydroxide ions. This means that the relatively concentration of hydroxide ions will always be lower than hydronium ions in an acidic solution. The reason for this is that in a neutral solution, the concentration of both hydronium ions and hydroxides ions are equal (both are 10-7). By making the concentration of hydronium ions greater than the concentration of hydroxide ions, the solution becomes acidic.
How do hydroxyl ions and hydronium ions affect pH?
As the concentration of hydronium ions (H+ ions) increases or as the concentration of hydroxyl ions (OH- ions) decreases, the pH of the solution decreases
How is concentration of hydronium ions affected when a solution of acid is diluted in water?
their is an increase in ion concentration
A solution has a hydroxide concentration of 0.0000125 M What is the concentration of hydronium ions in the solution?
8.0*10^-10 m
Is 9 the pH of equal numbers of hydronium ions and hydroxide ions?
No. pH is the negative logarithm of the concentration of the hydronium ion. Equal numbers of hydronium ions and hydroxyl ions occurrs only when a solution is neutral.
Are hydronium ions contributed to a solution by a base or acid?
Acids have more hydronium than hydroxide. Bases are the reverse of that.
How is the strength of a salt determined using the pH scale?
pH is a measure of the concentration of hydronium ions in a solution. pOH is a measure of the concentration of hydroxide ions in a solution. When a salt is placed into a solution (typically an aqueous solution), the cation and anion can either dissociate completely or partially, and can react with other ions in solution. If the salt pulls hydroxide ions out of solution, the solution becomes more acidic, and if the salt pulls hydronium ions out of solution, the solution will become more basic. So, if you want to determine the "strength" of a salt, add it to water and measure the hydronium ion concentration of that solution.
What ions are measured with a pH scale to determine the acidity of a solution?
The inverse logarithm of the concentration of hydronium ions in a water solution; basicaly, how acidic a solution is.
What is the measurement system called that indicate the concentration of H ions in solution?
The pH system is used to indicate the concentration of hydronium ('H+') ions in solution. It is governed by the equation pH = -log[H+]
How would you Calculate the H3O ion concentration in a solution with pH3 and a solution with pH8?
In a solution, hydrogen ions normally bond with molecules of water, forming H3O+ (hydronium) ions. Thus, the concentration of the hydronium ions will be the same as the concentration of hydrogen ions, which is related to the pH of a solution according to the following equation: pH = -log[H+] = -log[H3O+] This equation can be solved for the concentration of hydronium ions: [H3O+] = 10-pH Thus, for a solution with a pH of 3, the concentration of hydronium ions will be 10-3 = 0.001 moles/liter, and for a solution with a pH of 8, the concentration of hydronium ions will be 10-8 = 0.00000001 moles/liter.
What is the concentration in molarity of hydronium ions in a solution at 25 degrees Celsius with pH4.282?
