WebbSolution: As H Cl solution is acidic in nature and the pH of an acidic solution cannot exceed more than 7 Thus, the answer must be 6.9586 We can also find this answer through calculations From acid, [H +] = 10−8 M But the [H +] ions from water, i.e., [H +] = 10−7M cannot be neglected in comparison to 10−8M The pH can be calculated as follows WebbHence, the pH of 1 × 10-9 M HCl solution is 6.99.

Webb8 apr. 2013 · 1 Answer Sorted by: 7 For (a), the Henderson-Hasselbalch equation, p H = p K a + log ( [ A X −] / [ H A]), comes in handy. Because your molarities and volumes of the acid and its conjugate base are equal, this indeed reduces to simply p H = − log ( 6.3 ⋅ 10 − 5). WebbTherefore, the pH of the solution is 8.10. ... (HCl), we can assume that its contribution to the concentration of H+ ions is negligible. Therefore, we can write: [H₂NC2H4NH₂^+] = [OH^-] = x (let's assume) [H₂NC2H4NHCI] = 0.0400 M. …
WebbWe will calculate the pH of 25 mL of 0.1 M HCl titrated with 0.1 M NaOH. At each point in the titration curve, we will need to determine two quantities, the concentration of H + remaining in the solution, and the volume of the solution. From these, we can calculate the [H +] and, from that, the pH. 1.

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 Weak acids/bases only partially dissociate in water. Finding the pH of a weak acid is a bit more complicated. early stage diabetes risk predictionhttp://butane.chem.uiuc.edu/cyerkes/Chem102AEFa07/Lecture_Notes_102/Lecture27-102.htm early stage delicious instagramWebbThe pH of a solution is determined by taking the negative log of the concentration of hydrogen ions in solution. HCl is strong acid so it completely dissociates in solution. So adding .0001 M HCl is the same as saying that 1 *10-4 moles of H+ ions have been added to solution. The -log[.0001] =4, so the pH of the solution =4. Report an Error csu fresno chemistryWebbFinal answer. Step 1/3. GIVEN, 1] Concentration of HCL solution = 2.7x10^-3 M. Dissociation of strong acid [HCL]:-. HCL ↽ − − ⇀ H A + + Cl A −. So, concentration of HCL is equal to concentration of H^+. Concentration of H^+ = 2.7x10^-3 M.
