1. The mass of a weigh boat containing NaCl (58.44 ± 0.01 g/mol) was 3.6865 ± 0.0002 g. The mass of the empty weigh boat was 2.1022 ± 0.0002 g. The NaCl was quantitatively transferred to a 500.00 ± 0.20 mL volumetric flask, and the solution was diluted to volume and mixed. Calculate (i) the molar concentration of the prepared NaCl solution and (ii) the absolute uncertainty in the NaCl concentration. Report the concentration and absolute uncertainty using an appropriate number of significant figures.

Malic acid (C4H6O5) is a dicarboxylic acid that naturally occurs in the production of bignay wine. Maria was tasked to find out the acid content in a 200.0 mL wine sample by titrating it with a standardized solution of KOH. He was able to establish the working concentration of the KOH solution by using 39.12 mL of it to titrate a primary standard of KHP that weighed 3.021 g. The grams and %w/w of Malic acid present in the 200.0 mL wine sample were then determined by titrating a 20.00 mL aliquot using 48.95 mL of the standardized KOH solution. C4H6O5 (aq) + 2KOH (aq) ↔ K2C4H4O5 (aq) + 2H2O (l) Assume the density of the wine sample is 1.000 g/mL MM of KHP = 204.22 g/mol MM of C4H6O5 = 134.0874 g/mol ?

Tartaric acid, H2C4H4O6, is a diprotic acid that naturally occurs in the production of wine.

By pipet, 5.00 mLmL of a 0.823 MM stock solution of potassium permanganate (KMnO4) was transferred to a 50.00-mL volumetric flask and diluted to the calibration mark. Determine the molarity of the resulting solution.
Solutions of cyanide salts are still widely used in the extraction of gold metal from its ores. It is thereforenecessary to regularly monitor the quality of the reagents used to make such solutions.The purity of a sample of solid potassium cyanide is determined as follows: 5.00 g of the impure potassium cyanide is weighed off, and quantitatively transferred into a100.00 mL volumetric flask, dissolved and made up to the mark. A 10.00 mL portion of this solution is pipetted into a conical flask, and titrated with a 0.200 MKMnO4 solution. The endpoint of the titration is determined when the colourless solution in the conical flask turns abright pink due to the presence of excess permanganate ions. The average titration value is 20.69 mL of the KMnO4 solution.The reaction stoichiometry is as follows: 2KMno4(aq) + 3KCN(aq) + H2O(l) → 2MnO2(s) +3KOCN(aq) + 2KOH(aq) ૝1.1 Determine the percentage purity of the potassium cyanide.
