Can a solution have a negative ph
WebSolution for 25. Can the pH of a solution be negative? Explain. Consider three solutions, R, Z, and Q. • Solution R has[ H+ ]=0.0134. • Solution Z has a pH 6 times as large as solution R. • Solution Q has [OH-] half as high as that of solution Z. (a) Calculate the pH in solutions R, Q, and Z. (b) What is the ratio of [OH-] in solutions R and Z and … WebYes, it is possible for a solution to have a negative pH, but it has to be a relatively concentrated solution of a strong acid. False, because it is possible but only if the …

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. 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.
WebYes, negative pH is possible, but not in water as a solvent. The range of pH in water is 0 to 14 (to be more precise, it is -1.7 to 15.7, but for simplicity's sake, we start with the usual … WebAnswer (1 of 8): By definition, pH = -log[H+] so any value of [H+] > 1 M will coincide with a pH < 0. Many commercial “concentrated acids” have molarities greater than 1. * concentrated HCl is 12.1 M * concentrated HNO3 is 15.9 M * concentrated HClO4 is 11.7 M * concentrated H2SO4 is 18 M ...
Weba)Yes, for any solution with a concentration of acid greater than 1 M. b)Yes, for any solution with a concentration of base greater than 1 M. c)No, the pH range is 1–14. d)No, the definition of pH does not permit it to have a negative value.
