Looks like no one added any tags here yet for you.
Lyman series. Corresponds to ultraviolet Balmer (n1=2) corresponds to visible Paschen (n1=3) corresponds to infrared
31.5 - 25.0 = 6.5 mL 27.5/6.5 = 4.2 g/cm^3
Add drops of food dye to paper, place in beaker with 1M NaCl and allow it to come up
Do the same thing for part B but with metal ions and NH3
Distance component moved/ Distance solvent moved Can never be greater than 1 since its a ratio
Formal charge is Valence electrons - bonding electrons (Bonding electrons count as one each, so a single bond counts as one electron, a double bond counts as two)
Part A: Place crystals of compounds in watch glasses and leave them to see if they pick up or lose water
Part B: Clean crucible and heat it and then weigh. Weigh again with the sample, heat for 10 minutes and then weigh one more time.
Part C: Heat CuSO4 and then add water back into it. Look for physical and color changes
Part D: Heat compound in test tube to see if it is a hydrate
Efflorescent substances lose water to air
Hygroscopic substances gain water from humid air
Deliquescent substances take up so much water that they dissolve into water
Must release water on heating and be soluble in water
True hydrates are also reversible
A-
Insert a cuvet of red food dye into spectrometer. Get wavelength being absorbed.
B- Prepare penny solution by combining it with NO3. Find absorbance by placing into spectrometer. Find absorbance vs concentration and make calibration curve.
y=mx+b where absorbance is the y and you solve for x (concentration)
