what is p^H ? Write down the formula of p^H.
Answers
Answer:
pH = -log[H+]
where log is the base-10 logarithm and [H+] stands for the hydrogen ion concentration in units of moles per liter solution. The term "pH" comes from the German word "potenz," which means "power," combined with H, the element symbol for hydrogen, so pH is an abbreviation for "power of hydrogen."
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+]

Answer:
pH is a measure of the amount of hydrogen ion activity (H+) in a solution, and therefore its alkalinipH is a measure of the amount of hydrogen ion activity (H+) in a solution, and therefore its alkalinity or acidity. Even though pH is a unitless value but it is not a random scale. The value is due to the activity of H+ ion in the solution. pH is described as “the negative of the logarithm of the molar hydronium-ion concentration.”
pH = -log[H+]
