The formula for silver chloride is AgCl, formed by the combination of silver ions (Ag+) and chloride ions (Cl-), which are balanced to create an electrically neutral compound.
Step-by-step explanation:
The formula for the ionic compound silver chloride is AgCl. This is derived from the elements silver (Ag), which typically carries a +1 charge as an ion, and chlorine (Cl), which carries a -1 charge as a chloride ion (Cl-). When these two ions combine to form a compound, their charges balance each other out, resulting in an electrically neutral compound Ag+ + Cl- → AgCl.
Silver chloride is often encountered in chemistry, for example, in the reaction with sodium chloride (NaCl) and silver nitrate (AgNO3), which forms silver chloride as a precipitate: NaCl + AgNO3 → NaNO3 + AgCl.
