A tetraaquasalicylatoiron (III) complex calibration solution is prepared by transferring 0.50mL of a 0.00900 M salicylate dianion stock solution into a 10.00mL volumetric flask as well as diluting to the 10mL mark with 0.02 M iron(III) chloride that has been buffered to a pH of 1.6. Explain what is the molarity of the complex in the flask after dilution and would love the steps to get to this.
What [OH-] is necessary to start precipitation of Cu(OH)2 in a 0.0014 M copper(II) chloride solution?
Suppose 108.3 g of hydrogen peroxide decomposes and all of the oxygen gas is collected in a balloon at 1.00 atm and 25oC. Determine the volume of the balloon.
The decomposition of KClO3 proceeds spontaneously when it is heated. Do you think that the reverse reaction, the formation of KClO3 from KCl and O3 is likely to be feasible under ordinary conditions
What would be the major product if 1,4-dibromo-4-methylpentane was allowed to react with one equivalent of silver nitrate in ethanol. It is for a lab on the relative reactivity of alkyl halides in nucleophilic substitution reactions.
