Imagine you were working as a laboratory technician and your principal investigator asked you to develop Benedict’s test into a quantitative measure of the concentration of reducing sugar in a solution. To do this, you would first need to decide what to measure and then establish the relationship between your measurements and different concentrations of reducing sugars. Explain generally what you would decide to measure and how you would go about determining the relationship of your measurements to the concentration of reducing sugar.

I need a step by step explanation for this question.

What is the name of the chemical process in which chlorine is added to sodium to create salt?

Common oxidation states of mercury are +1 and +2. In the +1 oxidation state, mercury forms a diatomic cation. In the +2 oxidation state, mercury is a typical monatomic cation.   mercury(I)=Hg2+2mercury(I)=Hg22+     mercury(II)=Hg2+mercury(II)=Hg2+   Give formulas for the given mercury compounds. mercury(I) bromide:       mercury(I) oxide:       mercury(II) bromide:       mercury(II) oxide:
