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

put it into the 100mL beaker‚ add your 25mL of distilled water and stir to form the calcium chloride solution. Next‚ use stoichiometry to determine how much Na2CO3 and put it into a small paper cup. Then add the 25mL of distilled water to make the sodium carbonate solution. Mix the two solutions in the beaker and a precipitate of calcium carbonate will form instantly. Next‚ set up your filtration assembly. After the filtration assembly is ready‚ swirl the contents of the beaker to dislodge any precipitate
