Chemical Tests For Elements Present In Organic Compounds Assignment
Part II. Chemical Tests for Elements Present in Organic CompoundsA) Test for Phosphorus:1. Record your observations: When GH HNO3 was added, the ammonium molybdate had no reaction, but it was smoking.
When the elements were heated on a hot plate, there was a pale yellow color.B) Test for Nitrogen:1. Record the color of the litmus paperblue2. The complete and balanced chemical equation for the acid-base reaction between ammonia and water.NH3 + H20 > N Hy + OHbaseacidC) Test for Carbon and Hydrogen:1. What is the substance on the bottom of the beaker? condensation, water2. Where did this substance come from? combustion reaction from methanol.3. Is this a test for carbon, hydrogen, or oxygen?hydrogen4. Complete a balanced chemical equation for the complete combustion of methanol.CH3 OH + 02 602 + H201. Is this a test for carbon, hydrogen, or oxygen?cartoon2. Complete a balanced chemical equation for the reaction of CO2 with limewater.CO2 + Ca(OH) 2 > Ca Co3cy + H20( limewater )D) Test for Sulfur:1. Record your observations: The test tube that was in the water bath turned dark brown once the lead acetate was added, the test tube that was not heated turned light brown when leading acctate2. The dark-colored precipitate that is formed is PBS. (As in Part B above, NaOH is again used was added. decompose organic materials, so that an element can be tested.) What else is evidently necessary for this decomposition to go to completion? Heat is necessary for this decomposition to go to completion.Ex. If you heat up a protein, it will speed the reaction.
