I am grouping calcium chloride, citric acid , potassium iodide , sodium chloride ,and sucrose according to their properties.
I put sucrose and citric acid in one group and potassium iodide , sodium chloride, and calcium chloride in another group.
Is that correct?
It could be correct. It all depends upon which properties you are using to group.
I am using the melting points according to which melted first, second,and those that didn't melt within 2 minutes ; solubility in water; solubility in ethanol;and solution conductivity.
