Here we have to propose a method to measure the rate of decomposition of calcium carbonate to calcium oxide.
00:07
And this can be measured by several techniques depending on which equipment is available and which machines and what kind of analytical techniques can be accessed.
00:18
So the first one which can be done is a detection of co2 by titration.
00:26
So in this case scenario, we have some tank with decomposing co calcium carbonate and it releases co2.
00:59
This co2 is collected into the collection flask from which we collect from which we collect this flask.
01:20
Yeah, this flask has a liquid, and here co2 is dissolved in liquid.
01:27
So gaseo co2 becomes dissolved co2.
01:33
Then with every period of delta t, we collect some volume, and this volume is co2 dissolved in water.
01:51
And then we use titration to measure amount of co2.
02:11
Yeah, and this is an acid -based titration.
02:18
On the other hand, we might, depending on how much co2 is released, we can add it to solution of calcium hydroxide and do the gravimetric titration...
