The History of Paint Pigments Chem 111-404 April 24‚ 2013 Introduction: This report expresses five different pigments that were formed during chemical reactions. Three out of the total five reactions went through a metathesis‚ or double-replacment reaction. A metathesis reaction can be defined as “a chemical reaction in which an element or radical in one compound exchanges places with another element or radical in another compound.” (Webster).

prac‚ the aim was to determine which combinations of each solutions created precipitate and which did not. The prac proved to work in achieving this for most examples‚ although few were anomalous and did not give sound results. Take for instance‚ barium chloride and silver nitrate shown in the discussion. The result shown was cloudy and appeared to have precipitated where in actuality it should not have. It is also good to note that some instances of a precipitate not forming visibly may be due to

test. Hypothesis The hypothesis for this experiment stated that the sodium ion would color the flame in yellow‚ the potassium ion would color it in lilac‚ the lithium ion would color it in carmine‚ the calcium ion would color it in brick red‚ the barium ion would color it in apple green‚ and the copper ion would color it in green. Equipment * Graduated cylinder‚ 10-ml * Laboratory burner * Petri dish (8) * Wire loop‚ spatula * Safety goggles * Lab apron or coat

and Silver Nitrate there were no bubbles‚ however the substance turned a yellow-white colour after a few minutes. After a longer wait‚ the substance started to precipitate and the liquid started to become more solid. In the third reaction of which Barium Chloride and Sodium Sulphate were mixed‚ bubbles were again visible‚ however there were very few. After a couple of minutes the mixture turned very cloudy‚ into a solid white colour. 10 minutes later‚ the mixture was completely clear and the compounds

these changes. For the dryl’s solution the Paramecium were moving forward for about 79% of the time. When I was observing them they changed direction a few times but not a lot. They were moving at an average speed; not to fast or to slow. For the Barium solution the Paramecium were moving forward for about 41% of the time. When I was observing them they changed direction frequently instead of going forward for most of the time. They were still moving at an average speed. For the Sodium solution
