Can a ph be negative

WebSep 16, 2024 · Knowing the dependence of $pH$ on $[H_3O^+]$, we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic. This is known as the $pH$ scale. The pH scale is the range of value s from 0 to 14 that describes the acidity or basicity of a solution. You can ...

Since pH can be affected by chemicals in the water, … WebDec 24, 2024 · The pH equation can be seen as follows: pH = -log 10 [H 3 O +]. The equation can sometimes be seen as pH = -log 10 [H +]. Know that whether the equation has H 3 O + or H +, they are the same. It is not vital to have a firm understanding of what a negative log is to calculate pH.

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 ... WebCan an acid have a negative pH? If your acid solution is stronger than 1N, then you will get a pH less than 0 (a negative pH). It’s possible. If the molarity of hydrogen ions is greater than 1, you’ll have a negative value of pH. For example, you might expect a 12 M HCl solution to have a pH of -log(12) = -1.08.
