NettetThe pH of an aqueous solution is based on the pH scale which typically ranges from 0 to 14 in water (although as discussed below this is not an a formal rule). A pH of 7 is considered to be neutral. A pH of less than 7 is considered acidic. A pH of greater … Nettet14. aug. 2024 · Because the initial quantity given is K_b rather than pK_b, we can use Equation \ref {16.5.10}: K_aK_b = K_w. Substituting the values of K_b and K_w at 25°C …
Nettetph-wert is a measure of how acidic/basic water is. The range goes off 0 to 14, with 7 being neutral. pHs of less than 7 enter acidity, whereas a pH of greater than 7 indicates a base. The pH of water is a really important measurement concerned water quality. NettetpH is a logarithmic measure of the hydrogen ion concentration of an aqueous solution pH = -log[H +] where log is the base 10 logarithm and [H +] is the hydrogen ion …
