The correct formula for the ionic compounds formed from the given anion and cation is to be written. Concept Introduction: Ionic compound is a compound comprising ions having electrostatic interaction between them which is termed as ionic bonding. The element symbols and subscripts in an ionic compound are represented with the help of a chemical formula. Rules for writing formula for ionic compounds: The cation is given first in the formula. In the formula the subscripts must produce an electrically neutral formula unit. The subscripts must be the smallest set of whole numbers possible. The finished formula for substance does not include the charges on the ions. When a subscript is 1 it is left off, no subscript implies as subscript of 1.

Solution Summary: The author explains the correct formula for ionic compounds formed from the given anion and cation.
Write the empirical formula of the compound formed by (a) Al3+ and Cl - ions, (b) Al 3+ and O2 - ions, (c) Mg2+ and NO3 ions.
When 25 g of lead (II) nitrate, Pb(NO3)2, is mixed with 15 g of sodium iodide in water, a
reaction occurs and this produces sodium nitrate and solid lead (II) iodide.
(a)
Write a balanced equation for the reaction.
(b)
Calculate the theoretical amount of lead (II) iodide produced.
Some salts make hydrates when there is moisture around. Some hydrate samples can absorb lights in visible legion. Therefore, they show some colors. Thus, hydrates can be used to detect the moisture in the environment.
Let's say you are working in a laboratory with a group and you are the only student who has taken chemistry courses. Your laboratory received a sample of cobalt(II) chloride which has the formula CoCl2·xH2O. Let's say your boss asked you to find the formula of this hydrate salt sample since you are the only chemist there. From your laboratory experience, simply explain the experimental procedure you would follow to find the formula of this unknown sample.
Then, use the given data for the calculation part.
Mass of crucible: 32.27g
Mass of crucible + unknown hydrate: 33.92 g
Color of unknown hydrate: purple
Mass of crucible + anhydrous form of hydrate: 33.41 g
Color of anhydrous form: sky blue
