Web参考答案： 在纯水中，[H+]=[OH-]，故 pH=-lg[H+]＝-lg[1．375×10^-7]=7-0.14＝6.86 其pH值为6．86。 WebThe pH Scale provides a range of acidic, neutral and basic solutions between 0-14. The pH scale is directly related to the OH- concentration while inversely related to the H+ concentration. A pH value increases as the OH- ion concentration increases, while the H+ ion concentration decreases with the increasing pH value.
WebJun 14, 2013 · Converting [H+] to pH, pOH, and [OH-] What is pH? pH is the measure of the hydronium ion concentration in a solution. The scale runs from 0-14, with the lower numbers indicating higher concentration of the hydronium ion and therefore an increase in acidity. A similar scale exists for the hydroxide ion. WebSep 19, 2024 · The concentration of H 3 O + in a solution can be expressed as the pH of the solution; pH = − log H 3 O +. The concentration of OH − can be expressed as the pOH of the solution: pOH = − log [ OH −]. In pure water, pH = 7.00 and pOH = 7.00. References Petrucci, et al. "Self-Ionization of Water and the pH Scale."
WebThe pH scale is used to classify substances as acids and bases. The scale goes from 0 to 14. Things that are acids have a pH number that is less than 7. The lower the number, the stronger the acid. ... (H+) or hydroxide ions (OH-). Solutions are classified as acids or bases depending upon what kinds of ions they release. Acid solutions have
WebThus, the pH of an acidic solution of HNO 3 (10 –3 M) = 3, a basic solution of KOH having [OH –] =10 –4 M and [H 3 O +] =10 –10 M will have a pH = 10. pH of acids is generally less … irish passport chat onlineWebJun 1, 2016 · Explanation: [H +] → pH = −log[H +] = pH. [OH −] → pH = − log[OH −] = pOH. pH → [H +] = 10−pH = [H +] pOH → [OH −] = 10−pOH = [OH −] 14 −pH = pOH. 14 −pOH = pH. … port authority office of medical servicesWebMar 16, 2024 · The pH to H+ formula that represents this relation is: \small \rm {pH = -\log ( [H^+])} pH = −log( [H+]) The solution is acidic if its pH is less than 7.
