The diprotic acid lactic acid is produced as a result of anaerobic respiration. Raquel titrates the lactic acid in a yogurt sample according to the equation below. H2C3H4O3 + 2KOH → K2C3H,O3 + 2H2O 16.35 mL of 0.05 M KOH reacts with 40.00 mL of the analyte sample. What is the concentration of the lactic acid in the sample? [?]x 10 M H2C3H4O3 Coefficient (green) Exponent (yellow) Enter

CHEMISTRY (Please write the complete solution legibly. No long explanation needed. Answer in 2 decimal places. Box the final answer.) 25.00 mL of a solution of phosphoric acid, H3PO4, was titrated with 0.500 M NaOH. a) Write the balanced chemical equation for this reaction.b) If 35.92 mL of NaOH solution were needed to reach the end point in the titration, what is the molarity of the H3PO4 solution?c) How many grams of H3PO4 were present?

A titration is carried out to determine the concentration of the acid in an old bottle of aqueous HClHCl whose label has become unreadable. What is the HCl concentration if 75.3 mL of 0.250 M NaOH is required to titrate a 10.0 mL sample of the acid?

O SIMPLE REACTIONS Determining the molar mass of an acid by titration Jacqueline ant An analytical chemist weighs out 0.083 g of an unknown monoprotic acid into a 250 mL volumetric flask and dilutes to the mark with distilled water. She then titrates this solution with 0.0900M NaOH solution. When the titration reaches the equivalence point, the chemist finds she has added 20.0 mL of NAOH solution. Calculate the molar mass of the unknown acid.

You are preparing standard acid and base solutions for the laboratory, using potassium hydrogen phthalate (KHC₈H₄O₄, abbreviated KHP) as the primary standard. KHP (molar mass = 204.22 g/mol) has one acidic hydrogen. You prepared solutions of both NaOH and HCl. It took 22.65 mL of the NaOH solution to titrate (react exactly with) 1.55 g KHP. It then took 32.35 mL of HCl solution to titrate 25.00 mL of the NaOH solution. What is the molarity of the HCl solution?

NaHCO3(s) + HC2H3O2(aq) → NaC2H3O2(aq) + H2O(l) + CO2(g) A student designs an experiment to study the reaction between NaHCO3 and HC2H3O2. The reaction is represented by the equation above. The student places 2.24 g of NaHCO3 in a flask and adds 60.0 mL of 0.875 M HC2H3O2. The student observes the formation of bubbles and the flask gets cooler as the reaction proceeds. (b) Based on the information above, identify the limiting reactant. Justify your answer with  Calculations. (c) The student observes that the bubbling is rapid at the beginning of the reaction and gradually slows as the reaction continues. Explain this change in the reaction rate in terms of the collisions between reactant particles.

Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits.

The flask contains 10.0 mL of HCl and a few drops of phenolphthalein indicator. The buret contains 0.280 M NaOH. It requires 17.9 mL of the NaOH solution to reach the end point of the titration. What is the initial concentration of HCl? concentration: М НСІ

If 47.1 g of C₂H5OH (MM = 46.07 g/mol) are added to a 500.0 mL volumetric flask, and water is added to fill the flask, what is the concentration of C₂H5OH in the resulting solution?

A solution contains 8.85×103 M potassium fluoride and 1.45x102 M ammonium carbonate. Solid lead nitrate is added slowly to this mixture. What is the concentration of carbonate ion when fluoride ion begins to precipitate? [carbonate] = M
