Answer #1

The flame test is used to determine the presence of a particular metal ion in the given salt. Metals change the color of a flame when they are heated in it. Different metals give different colours to the flame,

Flame test for all salts (calcium oxide, calcium sulfate or calcium carbonate )gives the same color that is yellowish-red. so the flame test is not helpful to distinguish the among calcium salts.

when heated the metal ion electrons gain energy and jump to higher energy levels which are unstable. while coming back electrons release energy in the form of light which varies from one metal ion to another metal ions. so it leads characteristic color for each metal ion.

You are interested in the effect of copper sulfate on mucus cells in the gill filaments of eastern mosquitofish. You wish to determine whether a 24 hour exposure to copper sulfate will reduce the number of mucus cells. Select an appropriate statistical test to determine whether the number of mucus cells/mm2 differs between the gill filaments of separate treatment and control mosquitofish. Use the Mosquitofish Dataset and assume all data are normally distributed. What type of test did you perform?...

You have been tasked with determining the concentration of Ca2+ in an unknown solution of calcium carbonate (CaCO3). You titrate 50.0 ml of the unknown solution with 0.0250 M EDTA. It requires 16.85 ml of EDTA to reach the equivalence point. Determine [Ca2+] of the unknown solution, in ppm. Recall that ppm (parts per million) is equal to mg/L. 2. If a sample of tap water contains 400 ppm of Ca2+ and 80 ppm of Mg2+, what is the hardness...
