WebThe pKa measures how tightly a proton is held by a Bronsted acid. A pKa may be a small, negative number, such as -3 or -5. It may be a larger, positive number, such as 30 or 50. The lower the pKa of a Bronsted acid, the more easily it gives up its proton. The higher the pKa of a Bronsted acid, the more tightly the proton is held, and the less ... WebWhen you are given the molarity of an acid solution, and asked to determine the pH, a molarity greater than 1 produces a negative pH. Is this possible? Barry Bosco It's possible.

WebApr 8, 2024 · 1 Answer. You are most likely getting an inaccurate value. As anticipated in Poutnik's comment above is difficult to reliably measure a p H of very acidic solution but the p H scale is indeed open, and negative p H are a real thing. It is easy and more meaningful to state a very high concentration or activity rather than reporting inaccurate p H. WebI have a Ph.D. in Social and Personality Psychology.

WebSep 8, 2024 · Although pH values usually range from 0 to 14, it is definitely possible to calculate a negative pH value. A negative pH occurs when the molar concentration of hydrogen ions in a strong acid is greater than 1 N (normal). You can calculate a negative pH when an acid solution produces a molar concentration of hydrogen ions greater than 1. t4 levels in childrenWebFeb 15, 2015 · By either definition pH can be negative in concentrated solutions of … t4 ligase inactivationWebpH values are determined on a logarithmic scale. pH values are reported as a number between 0 and 14 as a standard pH unit. This unit is equivalent to the negative logarithm of the hydrogen ion molar concentration (-log(H+)) in the solution. Depending on the accuracy of the measurement, the pH value can be carried out to one or two decimal places. t4 levels in thyrotoxicosisThe answer is yes! The pH scale usually runs from 0 to 14, but if the molarity of hydrogen ions in a strong acid is greater than one you’ll calculate a negative pH value. For example, the calculated pH of 12M HCl (hydrochloric acid) is: pH = -log [H +] pH = -log [12] pH = -1.08.
