Help Experiment 29 Post lab question #2 The solid KIO3 is diluted shy of the 100mL mark in the volumetric flask. does this technique error result in a reported molar concentration of KIO3 that is too high or too low? Explain. As a result will the reported molar concentration of the standardized Na2S2O3 solution be too high, too low, or unaffected? Explain
With wet beriberi, peripheral vessels dilate and cardiac muscle looses its contractility. also, alpha-ketoglutarate is found in high concentrations. this is thought to be caused by
