A titration of sulfates in a 5.00 mL sample of drinking water with 10.0 mM (millimolar) of barium acetate as the titrant is carried out. A microflow pump was used instead of a buret, set at a flow rate of 0.122 mL/min. After 200 seconds has passed, what is the concentration of sulfates in the drinking water sample.
Predict the products for the following set of reactants- PCl3(l) + H2O(l) ? (You are just asked to determine the products and not necessarily balance the equation)
Method for Trapping a Gas, The decomposition of 3-sulfolene to form 1,3-butadiene generates 1 mole of sulfur dioxide gas per mole of 1,3-butadiene. Substantial quantities of SO2 would be generated if this decomposition were carried out on a large ..
