Pigments were first extracted from tomato paste by a 50/50 mixture of acetone/hexanes; these miscible molecules act together as one organic solvent. Pigments choose the organic layer over the tomato paste with water‚ which allowed for their extraction. K2CO3 is an ionic base that was added to deprotonate the citric acid. The ionic product of the reaction in figure 3 now prefers the aqueous layer‚ which serves to wash the pigments of the acidic impurity. Saturated NaCl pulls any water into the

abundance of success people sacrifice many things. Richard Rodriguez is a wonderful example of this statement. In his book‚ “The Achievement of Desire‚” he writes‚ “I was able to frame the meaning of my academic success‚ its consequent price- -the loss” (517).

If the CIS wants to expand to grow revenue I believe that they should
