chemical equation:
4. add copper (ii) nitrate to ammonium hydroxide in a test tube. for writing the equation, the roman numeral indicates the charge of copper. caution: ammonium hydroxide produces very pungent ammonia gas, quickly add ammonium hydroxide to the test tube and immediately replace cap.
observations:
reactants:
products:
chemical equation:
5. add a few crystals of cobalt (ii) chloride hexahydrate into the large test tube. add one drop of water (or enough to just dissolve the crystals). heat the test tube with a bunsen burner. caution: cobalt (ii) chloride is toxic by ingestion, absorption through tissue and inhalation of powder.
observations:
reactants:
products:
chemical equation:
6. add zinc sulfate to sodium phosphate. note: zinc always takes a +2 charge.
observations:
reactants:
products:
chemical equation:
7. add lead (ii) nitrate to sodium iodide. the roman numeral indicates lead has a +2 charge. note: due to the toxicity of lead, be sure to dispose of any lead into the “heavy metal waste” container.
observations:
reactants:
products:
chemical equation:
8. place a small amount of copper turnings rolled into a ball in a 50 ml beaker on top of wire gauze placed on the bunsen burner and turn on the heat. assume this reaction generates copper with a +2 charge.
observations:
reactants:
products:
chemical equation:
9. while holding the test tube in your hand, add hydrochloric acid to sodium hydroxide. caution: hydrochloric acid is corrosive and sodium hydroxide is caustic. both of these substances are at high concentrations and should be handled with care.
observations:
reactants:
products:
chemical equation:
10. add a few drops of dimethylglyoxime (dmg) indicator to a solution of nickel nitrate. add magnesium metal to the solution. note the dmg is not a reactant or product. it merely allows the reaction to be observed easily.
observations:
reactants:
products:
chemical equation:
i just really need on how to get the reactants, product and chemical equation.
