Webb12 juni 2024 · A fundamental equation to know regarding pH is that (near 25oC ), pH+pOH = 14.00. That is, near 25oC, the sum of the pH and pOH is always 14.00. Therefore, pOH = 14.00 − pH = 14.00 − 7.0 = 7.0. Since the pH and pOH are equal, this solution is said to be neutral; i.e. it is neither acidic nor alkaline (basic). Answer link.

Given, a solution has pOH equal to 13 at 298 K. Therefore, pH=14−13=1. Therefore, the solution is highly acidic. So, the correct option is … design and build astute payrollWebbThe strategy here is to calculate the pOH and then, using the pH + pOH = 14 relationship, determine the pH. NaOH is a strong base, so [OH –] = [NaOH], and therefore, the pOH is: pOH = -log 0.850 = 0.0706 The pH then is equal to: pH = 14 – pOH = 14 – 0.0706 = 13.9 As expected, the pH is very high because it is a solution of a strong base. chubb limited press release
