Can you please further explain to me what I have to do to find the theoretical pH? I've prepared a 0.1 M Acetic acid by measuring out 5.0 mL, of 1.0 acetic aci and 45 mL of deionized water. Plus a additional of 1.00 mL of 1.0 M hydrochloric acid. The Ka is 1.8 × 10 ^ 5.
By reference to the reacting ratio of HCL and NaOH, deduce the number of moles of NaOH required to reach Equivalence. Btw I did the first part of the question so this is a follow up.
Sodium hydroxide (NaOH) is a reagent in the form of crystals and is highly hygroscopic. It is advisable to standardize it when it is desired to use it in acid standardization solutions. Knowing that 12g of the base (NaOH) were used to prepare 1L of solution, determine the actual concentration of the solution (NaOH) for a 50mL sample where 55 mL of 0.3N hydrochloric acid were used, and the volume of the said base to prepare 1L of 0.01N solution. (Data: Molar Mass of NaOH = 40.0g/mol).
10.0 cm³ of a solution of a strong acid with a pH of 3 is added to a volumetric flask and the total volume is made up to 1.00 dm³ by adding distilled water. The resulting solution is then thoroughly mixed. What is the pH of the diluted solution?
A reaction was carried out between 18 ml of a 0.05 M solution of hydrochloric acid with 24 ml of a 0.2 M solution of ammonium hydroxide with (Kb-1.8x 10-5) at a temperature of 25 C. What is pH and pOH respectively of the solution product after the reaction. Note that the molecular weight of ammonium hydroxide is 35 g /mole and the molecular weight of hydrochloric aeid is 36.5 q/mole.
Calculate the pH of a solution containing a salt AcNa derived from a strong base (NaOH) and a weak acid (AcH), like CH3COONa, KF, NaNO2 and so on. In this case two processes have to be considered: 1. Dissociation of the salt, within the assumption that the salt is a strong electrolyte: AcNa → Ac- + Na+, for instance: CH3COONa → CH3COO- + Na+ 2. the hydrolysis of the water Ac- + H2O ⇌ AcH + OH-, for example: CH3COO- + H2O ⇌ CH3COOH + OH- knowing that the initial concentration of the salt is 1.95 M and the acid dissociation constant, Ka , is 1.21e-7.

Approximately 6 mL of conc. perchloric acid ( 72% ) was transferred to a bottle and diluted with about 1 liter of water. A sample containing 251.5 mg of primary standard Na2B4O7.10H2O (Fwt= 382g/mol) required 27.41 mL of the HClO4 solution to reach the methyl red end point. What is the molar concentration of the HClO4 solution? Na2B4O7.10H2O + HClO4 ------------> NaClO4 H2B4O7.10H2O
