WebApr 26, 2024 · The pH scale is a numeric scale, running from 0 to 14. On this scale, a pH level of 7 indicates neutral (neither acidic nor alkaline), a pH level less than 7 indicates acidic, and a pH level greater than 7 indicates alkaline. The equation that defines pH is: pH=-log [H+] concentration WebA solution of a strong acid at concentration 1 M (1 mol/L) has a pH of 0. A solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. Weak acid/base
WebJan 30, 2024 · Find the pH of a solution of 0.002 M of HCl. Find the pH of a solution of 0.00005 M NaOH. Solution The equation for pH is -log [H+] [ H +] = 2.0 × 10 − 3 M p H = − log [ 2.0 × 10 − 3] = 2.70 The equation for pOH is -log [OH -] [ O H −] = 5.0 × 10 − 5 M p O H = − log [ 5.0 × 10 − 5] = 4.30 p K w = p H + p O H and p H = p K w − p O H then WebThe pH scale ranges from 0 to 14, with 7.0 being neutral. Solutions with a pH below 7.0 are acidic while solutions with a pH above 7.0 are basic (or alkaline). Since the pH scale is …
WebSep 9, 2024 · The pH value of a solution reflects the relative concentration of hydrogen ions (H+) or protons to the concentration of hydroxide ions (OH-) in a solution. Solutions with a pH value less than 7 are acidic and those with a value greater than 7 are basic, or alkaline.
