its flame test. Purpose Observe the characteristic colors produced by certain metallic ions when vaporized in a flame. Identify unknown metallic ions by means of its flame 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

how we were able to find the limiting reagent in this lab. A limiting reagent is the chemical that will be used up first. Many calculations had to be made throughout this lab. Some of the calculations we made were finding the amount of moles of Sodium Hydroxide and Calcium Chloride from the eight different test tubes. Sunny Patel Chem 101 10-13-09 Discussion and Conclusions The whole purpose of this lab was to apply stoichiometry to a chemical reaction. Our calculations all depend on

lattice is collapses and the solid is converted into liquid. The trend in structure is from the metallic oxides containing giant structures of ions on the left of the period via a giant covalent oxide in the middle to molecular oxides on the right. Sodium peroxide‚ magnesium oxide and aluminum oxide are metallic oxide which have high melting and boiling point compared to other period 3 oxide. This is due to their giant ionic structure and the strong ionic bond. Strong ionic bond in the molecule need
