ilil Names and formulas of fomle compounds and their parent resulting from the presence of ions. Most ions composed of two colorless ions appear white. Sodium chloride e is turquoise (a blue-green color). Since the Many ores and precious stones have colors is white, therefore, sodium ions and chloride color in any compound. Copper (l) chloride ion is colorless, the color ions are both colorless and will not give of turquoise must come from the copper(II) ion. Look at the samples of the ionic compounds listed in the table- these are located in the area in the lab. Do not take these to your bench top. Complete the table; an example has been provided for you. Write the name of By a process of eliminating ions that are c ion that must be the compound. Record the color. olorless, identify and write the formula for the to the compound. Write the formula of the anion (negative compound. Write the formula and name of the parent acid. The formula of acid can be obtained by placing the righ a parent of the anion that will balance the total charge to zero. number of hydrogen ions(H) in front Color Formula Anion Paren. A Formula Name of ion Formula Formula Both pos ions are POH phosphoric acid NasPO 5odium Whitei CoCl K CrO CuSO CaCO MgSO NiChExplanation / Answer
Naming ionic compounds classified as
1) Without a transition metal (S-block elements)
a) metal ion name wont change with charge
b) anion name ends with "-ide"
NaCl:
Na+: sodium (s block metal)
Cl-: chloride
NaCl: Sodium chloride
2) transition metal
a) Charge on transition metal is shown as Roman numeral
b) anion name ends with -ide
example:
CuCl2:
Cu+2: copper(II)
Cl-: chloride
CuCl2: Copper(II) chloride
Color: transitional metal ions with unpaired electrons in d-orbital show color
