Question

what is precipitation reaction​

Answer 1

Answer:

A precipitation reaction refers to the formation of an insoluble salt when two solutions containing soluble salts are combined. The insoluble salt that falls out of solution is known as the precipitate, hence the reaction's name. Precipitation reactions can help determine the presence of various ions in solution

Rules of Precipitation

• Nitrates (NO3–): All are soluble.

• Potassium (K+), sodium (Na+), and ammonium (NH4+) salts: All are soluble

.

• .Chlorides (Cl–), bromides (Br–), and iodides (I–): All are soluble except silver (Ag+), lead (II) (Pb2+), and mercury (II) (Hg2+) salts

Precipitation reactions are useful in determining whether a certain element is present in a solution. If a precipitate is formed when a chemical reacts with lead, for example, the presence of lead in water sources could be tested by adding the chemical and monitoring for precipitate formation

Net ionic equations

Hear this out loud

Hear this out loudThe net ionic equation only shows the precipitation reaction. A net ionic equation must be balanced on both sides not only in terms of atoms of elements, but also in terms of electric charge. ... If all products are aqueous, a net ionic equation cannot be written because all ions are canceled out as spectator ions
