WebOct 22, 2024 · Thus, pH = 14 - 4.74 = 9.26. CASE TWO: after addition of 12.5 mL of HBr. Number of moles of H^+ present= (The initial concentration of H^+) × ( addition of 12.5 mL of HBr) = 0.220 × 12.5 × 10^-3= 2.7 × 1O^-3 mol. Number of moles of C5H5N present = 25 × 10^-3 × 0.220. = 5.5 × 10^-3 mol. Therefore at equilibrium; WebMar 6, 2024 · Calculate pH by pH + pOH = 14 According to the theory 1, OH - concentration is 0.1 mol dm -3 Now, you can use the equation 3 to calculate pOH with known OH - concentration. pOH = -log 10 [OH -(aq)] pOH = -log 10 [0.1] pOH = 1 Now, use the equation 3 to find the pH pH + pOH = 14 pH + 1 = 14 pH = 13 pH of 0.1 mol dm-3 KOH solution is 13. …
WebJun 6, 2016 · Hydrochloric acid is a strong acid that completely dissociates in water. For a 0.025 M HCl solution the concentration of the hydrogen ions, [H+], is 0.025 moles/liter (i.e. 0.025 M). pH is defined as −log[H+]. Substituting 0.025 into the equation for pH we find that the 0.025 M HCl solution has a pH of -log (0.025) = 1.60. Answer link. WebApr 16, 2024 · The pH value can vary from 0 to 14. Solutions with a pH between 0 and 7 are acidic, while those with a pH between 7 and 14 are basic. Pure distilled water should be neutral with a pH of 7, but because it absorbs carbon dioxide from the atmosphere, it's actually slightly acidic with a pH of 5.8. TL;DR (Too Long; Didn't Read)
