Unformatted text preview: flask 10 mL of the Ca(IO3)2 solution using a volumetric pipette. Then add 10 mL of 1.00 M HCL to the Ca(IO3)2 and KI to the flask by using a 10 mL graduated cylinder. After all the components are added, the solution color should be brown. Then titrate with the Na2S2O3 until a yellow color change is noticed. At this point, 10 drops of 1% starch indicator should be added and then return to titrating the solution until it is colorless. Record the final buret reading and then repeat the titration 4-6 more times. This would require the Erlenmeyer flask to be prepared again and the steps involved in the titration to be repeated. This should conclude the first part. For the 2 nd part repeat the same procedure, but use (calcium iodate in KIO3) instead making sure to record all the necessary data.
