The 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. See more Of course, calculating a negative pH is different from an aqueous solution actually havinga negative pH. The pH equation assumes complete dissociation of a strong acid into its ion. It … See more It turns out experimental verification of negative pH values is slightly complicated. There isn’t a special litmusor pH paper that changes color at a negative value. Glass pH meters don’t give accurate pH measurement under … See more WebIn this JC2 webinar we want to discuss if pH of an acidic solution can be negative.Let's …

Although the impact on rhizosphere soil microbial communities and metabolites after applying Trichoderma are still unclear. In this study, we applied the … 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 ... china high school classroom
