The metal in a metal complex acts as a:

A white precipitate of K2SO4 may be obtained during the identification/test of cobalt ion. This may hinder the true color of the cobalt complex.  Which of the following method is used in the experiment to minimize the interference of K2SO4 in the observation of cobalt complex?

Printed or stated directions regarding church practices and procedures as approved by religious leadership

What is the molecular weight of K3[Fe(C2O4)3].3H2O? Use 19K39, 26Fe56, 6C12, 8O16 and 1H1 Select the closest answer

The end point of the titration of oxalate with permanganate ion can be observed when the color of the solution turns to

Calculate the percent C2O42- by weight in H2C2O4 Use 6C12, 1H1 and 8O16

(This question ties to question 18) The balanced reaction between oxalate and permanganate ion is shown below.  5C2O42-  +   2MnO4  +  16H+  →  10CO2  +  8H2O  +  2Mn2+ During the standardization of KMnO4, a 28.0 mL of  KMnO4 has been used to neutralize 0.200 g of Na2C2O4 (MW = 134 g/mol). Based on the balanced reaction, determine the moles of permanganate KMnO4 in 28 mL Hint: Identify the mole ratio between oxalate and permanganate
