This is a dilution lab of acetic acid. There is 1.0M acetic acid with ph of 2.297, 0.1M acetic acid with ph of 2.69897, and 0.01M acetic acid with ph of 3.69897. They were all filled up to 50ml in a volumetric flask. How do you build the ICE table for the different concentrations?I have attached some images for extra information if needed.
How many milliliters of 0.800 M KOH should be added to 3.38 g of oxalic acid (C2O4H2) to give a pH of 4.40 when diluted to 500 mL? [For oxalic acid pK, = 1.250 and pK2 = 4.266]
H2Z is a diprotic acid with Ka1 = 3.0 × 10^-3 and Ka2 = 8.0 x 10^-8. Suppose you start with 1.00 L of 1.00 M H2Z(aq) and add 1.00 M KOH (aq) gradually. Calculate the pH at the following volumes of added strong base: a) 0.00 L; b) 0.50 L; c) 1.00 L; d) 1.50 L; e) 2.00 L. Report the pH values with 2 decimal places after dot. Write relevant chemical equations and show work on every part of this problem. f. Sketch the titration curve g. How many liters of 1.00 M KOH(ag) should be added to 1.00 L of 1.00 M H2Z to obtain a buffered solution with pH = 7.50? Hint to part g: you may calculate the moles of two salts in the buffer, then moles of K* ions in the salt, and finally consider that all K* ions come from KOH(ag).

Students Mola and Rity were tasked to analyze the acidity of a 10.0-mL fermented milk sample diluted with water in a 250-mL volumetric flask. Mola obtained a 15.0-mL aliquot of this solution, diluted it to 50.0 mL, and then titrated this diluted sample. Titration data were given to Rity and she found out that the 50.0-mL diluted sample contains 0.21 mmol of lactic acid. MW: Lactic Acid (90.08) a. What is the lactic acid concentration (in M) of the titrated sample? b. Determine the lactic acid content (in M) of the 10.0-mL fermented milk sample. c. What is the lactic acid concentration (in %w/v) of the 10.0-mL fermented milk sample?

Can someone help me with the problem below? CH3NH2 is a weak base (Kb=5.0×10−4), so the salt CH3NH3NO3 acts as a weak acid. What is the pH of a solution that is 0.0490 M in CH3NH3NO3 at 25 ∘C?
Maleic acid (H2C4H2O4, represented by H2M) is the precursor of malic acid widely used in industry. food as an acidulant and in the pharmaceutical industry it is used in the treatment of wounds. This acid can be determined by neutralization titration. Answer the items below about this determination. Considering a 15.0 mL sample of maleic acid-based product used in industry, determine the maleic acid concentration, in mol/L, in the sample knowing that 21.7 mL of a solution of 0.1120 mol/L NaOH for complete neutralization of this acid. How many grams of maleic acid were in the sample analyzed and what is its percentage (%, m/v) in the sample?
