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 ... WebSo, in fact, you can't measure negative pH value, meanwhile you can calculate negative pH values. For example 12 M of HCl is -1.8. Cite. 7th Feb, 2024. Neeraj Pandey.

WebPowerful acids may also have a negative pH, whereas strong bases could have a pH higher than 14. Only in an “aqueous solution” or water can pH have any meaning. Many substances, especially liquids, do not even have pH values. If there is no water, there will be no pH. For example, there is no pH value for gasoline, vegetable oil, or pure ... 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. hunter\u0027s longbow dead cells

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. 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. WebMar 14, 2024 · It is possible to get a negative pH or pOH when the concentration of hydrogen ions is greater than one. Yes, pH can have a negative value, although it is not … marvelous theatre review
