What are the 5 classes of reactions?
The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion.
What observation reveals a precipitate is formed in solution?
The identity of the precipitate can often be determined by examining solubility rules. It also occurs in single displacement when one metal ion in solution is replaced by another metal ion. Notice the new solid forming on the bottom of the tube.
Why does baso4 form a precipitate?
BaSO4, HgSO4 and PbSO4 are insoluble. A solution of barium chloride is mixed with a solution of potassium sulfate and a precipitate forms. Because it is insoluble in water we know that it is the precipitate. As all of the other substances are soluble in water we can rewrite the equation.
Is srso4 a precipitate?
Keep in mind that strontium hydroxide is only slightly soluble in water, but its dissociation will be aided by the fact that the hydroxide anions will form a precipitate with the copper(II) cations. so a precipitate of strontium sulfate will form.
Will a precipitate form when you combine two chemicals?
Tell students that a precipitate is an insoluble solid that forms when two solutions are combined and react chemically. Insoluble means that the solid will not dissolve.

Is insoluble in water while is highly soluble due to?
Be(OH)2 is insoluble in water while Ba(OH)2 is highly soluble due to. On moving down the group , lattice energy decreases with increase in size of cation.
Why LiCl is soluble in water?
In case of LiCl, the hydration energy is higher than the lattice energy. Hence, LiCl is water soluble. Due to higher polarization, LiCl has some covalent character. Hence, it is soluble in non polar solvents such as acetone.
