Fast pls i will give u like for sure solve this question correctly in 5 min pls A student analyzed a CaCO3 antacid tablet by neutralizing the base with an excess of .60 M HCL and back-titrating the excess with .50M NaOH. He recorded the following data: mass of tablet = 1.3g amount of active ingredient CaCO3 per label = 500 mg volume of HCl added: 25 mL initial buret reading : 34 mL final buret reading : 47.4 mL If the concentration of the provided HCl is actually higher than .60M, would the determined mass of CaCO3 in the antacid tablet be too high or too low?

A curious CHEM 32.1 student wanted to determine the levels of Fe (FM = 55.85), Al (FM = 26.982) and Pb (FM = 207.2) in a wastewater effluent from a powerplant near their place. To do so, he obtained 100 mL of the water sample for analysis. After appropriate sample preparation, he added10.00 mL of 0.100 M sodium tartrate to prevent the precipitation of Pb. Then, he added NH3 dropwise, which results to precipitation of hydrated Al(OH)3 and Fe(OH)3. After filtration and washing, the student ignited the residue, giving 0.6127 g dry Al2O3 (FM = 101.96) and Fe2O3 (FM=159.69). When heated under a stream of H2, Al2O3 is unchanged, but Fe2O3 was converted to Fe(s) and H2O(g) , giving a residue that weighs 0.4967 g. Meanwhile, he added excess amount of concentrated H2SO4 in the filtrate, which results to precipitation of PbSO4 (FM = 303.26) weighing0.1317 g after drying. Given these information, calculate the ppm Fe, ppm Al, and ppm Pb in the effluent.
