(b) What will the precipitate weigh after ignition at 800 °C? (c) What is the relative error (in percent) in the ignited precipitate due to the fact that some of the sulfate precipitated as Fe.(SO,), rather than BaSO,?Caustic potash that has been exposed to air is found on analysis to contain 90.00% KOH, 2.38% K2CO3 and 7.62% H2O. What weight of residue will be obtained if 1.00 g of this sample is added to 46.00 mL of 1.00 N HCl and the resulting solution, after neutralization with 1.070N KOH is evaporated to dryness?
