Method - Finding the amount of Calcium Carbonate in an Ore, by using Hydrochloric acid.
HCL 20ml for each sample of Calcium Carbonate
Calcium Carbonate ore sample (10g of each) -different
percent of carbonate in each ore
The tempature of the HCL
Amount of HCL
Amount of Carbonate (g)
We will be changing the percent of carbonate in the ore.
Measure out the carbonate and acid
Fill the conical flask with your acid and add your carbonate sample(1g). Make sure to start the stopwatch as soon as you begin.
The mixture should begin fizzing for a certain time. Stop the stop clock as soon as the bubbles stop.
Record the time, in seconds, and record it in some format, presumibly a table.
This is a pretty simple method of measuring the amount of carbonate in a ore. It can be useful in many ways - and methods like these are especially helpful education-wise. Feel free to use this as your own. No copyright claimed.
