Webso at the end (last problem), the PH value for neutral (equal concentration of H+ and OH-) water @ 50°C is 6.64. I've always assumed that only PH=7 is neutral. Does the neutral PH value of everything depend on temperature? In other words, does the [H+]= [OH-] concentration equilibrium change depending on the temperature? Answer • Comment ( 2 … WebYes if [HCl] = 1M then the pH = 0. Negative pHs indicate an acidic solution with a [H₃O⁺] > 1M — you can just plug the values in to the equation to find out an exact answer for any value. I also recommend reading this short article:

WebJan 6, 2024 · The base is a substance that produces OH- ions in solution. If hydrogen ions H + outnumber hydroxide ions OH -, the solution is acidic. The pH scale ranges from 0 to 14. Pure water is neutral and has a pH value of 7. When pH values are below 7, they correspond to acids, while values above 7 correspond to bases. Pure water is neutral. When an acid is dissolved in water, the pH will be less than 7 (25 °C). When a base, or specifically an alkali, is dissolved in water, the pH will be greater than 7. A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm has a pH of 0. A solution of a strong alkali, such as sodium hydroxide, at concentration 1 mol dm , has a pH of 14. Thus, measure… how is energy released from an atp molecule
