Calculate the ph of an aqueous solution
WebJan 30, 2024 · Answers. 1. Use the pH equation which is: pH = − log[H3O +]. 2. Use the pH equation pH = − log[H3O +] and pK w equation pKw = pH + pOH = 14. 3. Use the pOH … WebWhen you know pH, you can calculate concentration of H 3 O + ions from pH equation. Due to pH = 1, H 3 O + concentration is 0.1 mol dm -3. Due to dibasic acid, when sulfuric acid molecule dissociate, two H 3 O + ions are given. Therefore, concentration of sulfuric acid should be a half of concentration of H 3 O +.

WebCalculate the pH of an aqueous solution of sodium carbonate (a weak base) that has a concentration of 2.27 × 10-5 M hydroxide ions. Answer: 9.36 This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer WebApr 30, 2014 · Let's assume the solution is 0.1M. NaOH is a strong base, so this will produce 0.1mol/L of OH ions in solution. This will produce a pH of 13. You will need to take the negative log of 0.1 to find the pOH. This will work out to be 1. Since pH + pOH = 14 We can calculate the pH to be 13.
WebDec 6, 2024 · Sodium hydroxide is a strong base, which means that it dissociates completely in aqueous solution to produce hydroxide anions in a 1:1 mole ratio. NaOH(aq) → Na+ (aq) +OH− (aq) So your solution has. [OH−] = [NaOH] = 0.150 M. Now, the pOH of the solution can be calculated by using. pOH = − log([OH−]) −−−−−−−−−−− ...
