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.

A 244.5-g sample of ground water is analyzed for calcium. The Ca2+ in the sample is first precipitated and filtered-off as NH4CaPO4.7H20. This precipitate is dried and heated, releasing water and ammonia to yield anhydrous calcium pyrophosphate (CaP2O7). The mass of CaP2O, obtained is 0.0419 g. Give the calcium content of the ground water in parts per million (to three significant figures).
In the common process for the manufacture of nitric acid, sodium nitrate is treated with aq. sulphuric acid containing 95% H2SO4. In order that the resulting "niter cake" may be fluid; it is desirable to use sufficient acid so that there will be 34% H2SO4 by wt in the final cake. This excess H2SO4 will actually be in combination with the Na2SO4 in the cake, forming NaHSO4, although for purposes of computation it may be assumed to be free acid. The cake will contain 1.5% water and the reaction will go to completion, but 2% of the HNO3 formed will remain in the cake. Assume that the NaNO3 used is dry and pure. Calculate per 100 kg of NaNO3 charged: (a) wt and % composition of the niter cake (b) wt of aqueous acid to be used (c) wt of water vapor and nitric acid distilled from the niter cake.

4) A chemist was employed to analyse a particular lawn fertiliser, and dissolved 15.0g of the sample in water. Excess barium chloride was added to precipitate all the sulphate as barium sulphate according to the equation: Ba2+(ap)+SO42-(aq)-> BaSO4(s) When the precipitate was filtered, dried and weighed it had a mass of 4.67g. What was the percentage by mass of sulphate in the lawn fertiliser?
A plant manufacturing nails and screws uses a large pool (volume = 10,000 L) to collect and treat its residual wastewater before discharging it in a nearby stream. The manufacturing process makes use of a strong acid (HCl) and a weaker one (phosphoric acid, H3PO4; pKa1 = 2.148, pKa2 = 7.20, pKa3 = 12.15), before discharging them in the pool for treatment (neutralization). Once the pool is filled to its maximum capacity, a technician measures the chlorine and phosphorus concentrations in the wastewater to be 0.5 M and 1.0 M, respectively. Assume (i) that chlorine and phosphorus come only from HCl and phosphoric acid, respectively, and (ii) that no H+ was consumed (or neutralized) in the manufacturing process. (a) Knowing that the technician has to bring the pH of the waste water back to a minimum of 7.2 before discharging it in the stream, what is the minimum amount (in kg) of NaOH(s) (40 g/mol) that he has to add to the pool before discharging the waste water in the stream?
