WebThe greater the value of K a, the more favored the H + formation, which makes the solution more acidic; therefore, a high K a value indicates a lower pH for a solution. The K a of weak acids varies between 1.8×10 −16 and 55.5. Acids with a K a less than 1.8×10 −16 are weaker acids than water. If acids are polyprotic, each proton will have a unique K a.For example, H … WebMar 16, 2024 · The pH scale (pH) is a numeric scale used to define how acidic or basic an aqueous solution is. It commonly ranges between 0 and 14 but can go beyond these … gradpoint answers
How to determine the pH of a mixture of two weak acids?
WebMay 29, 2024 · (1) The pKa is less than 0 since you can't have an aqueous solution with a pH < 0. Thus if the pKa < 0, then the acid is considered to be completely dissociated in aqueous solution. But remember that one drop of water into a liter of concentrated sulfuric acid isn't an aqueous solution. WebJan 29, 2024 · A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. The conjugate base of a weak acid is a weak base, while the conjugate acid of a … Webarrow_forward. Calculate the pH of a weak base which dissociates as BOH ⇌ B+ + OH- ( like NH3 (g) + H2O (l) → NH4OH (aq) , where in water NH4OH ⇌ NH4+ + OH- ) knowing that the initial concentration of the base is 1.04 M, and the base dissociation constant, Kb , is 3.79e-10. pH ← please insert your value. arrow_forward. grad plus loan forgiveness
