1. In a redox titration, 12.50 mL of 0.800 mol/L K2Cr2O7 (aq) was used in an acidic solution to oxidize Sn* (ag) ions to Sn*en ions. The volume of K2Cr2O, (az) used was just sufficient to oxidize all the Sn2" of the Sn2 ag ions in the solution. What colour change indicated the end point of this calculation? Explain. 4+ in 10.0 mL of the solution Calculate the concentration

I just have some practice questions I need help on for Chemistry 30.
Further Analysis Questions In a redox titration, 12.50 mL of 0,800 mol/L K2CR2O7 (aq) was used in an acidic solution to oxidize Sn?* an) ions to Sn jons. The volume of K2C12O7 (aq) used was just sufficient to oxidize all the Sn²a) in 10.0 mL of the solution Calculate the concentration of the Sn2*ag) ions in the solution. What colour change indicated the end point of this calculation? Explain. 1. 2. What volume of 0.0500 mol/L KMNO4 (gg) is needed to oxidize all the Br (ag) ions in 25.0 mL of an acidic 0.200 mol/L NaBr (ag) solution? What colour change indicates the end point of the reaction? Explain. Copyright © 2007 Thomson Nelson
