What best describes a precipitate?
In chemistry, a precipitate is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid from solution is called precipitation. Often the precipitate emerges as a suspension. Precipitates can form when two soluble salts react in solution to form one or more insoluble products.
What indicates a precipitate is forming?
A precipitate is a solid formed in a chemical reaction that is different from either of the reactants. This can occur when solutions containing ionic compounds are mixed and an insoluble product is formed. The identity of the precipitate can often be determined by examining solubility rules.

What causes BaSO4?
1.1. 5 Barium Sulfate. Barium sulfate, BaSO4, is made by reacting barium hydroxide and other barium sources with sulfuric acid and has a long history as a translucent white pigment.
Is BaCO3 soluble in water?
Barium carbonate is a white powder. It is insoluble in water and soluble in most acids, with the exception of sulfuric acid. It has a specific gravity of 4.275.
Why is LiCl not soluble in water?
This is mainly because of the greater ionic character of LiF as compared to LiCl. The solubility of a compound in water depends on the balance between lattice energy and hydration energy. Hence, low lattice energy and greater covalent character are the factors making LiCl soluble not only in water, but also in acetone.
Why beso4 is soluble in water whereas baso4 is not?
Hydration energy and solubility are directly proportional while being inversely proportional to lattice energy. BeSO₄ has a high hydration energy while BaSO₄ has a high lattice energy meaning that BeSO₄ is more soluble in water.
What happens when LiCl is dissolved in water?
When some LiCl is dissolved in water, the temperature of the water increases. This means that: (A) the strength of the intermolecular forces between the water molecules is stronger than the bond energy within the LiCl lattice. (C) breaking the bonds between the lithium and chloride ions is an exothermic process.
Why does temperature increase when LiCl is dissolved in water?
The process of dissolving is exothermic when more energy is released when water molecules “bond” to the solute than is used to pull the solute apart. Because more energy is released than is used, the molecules of the solution move faster, making the temperature increase.
Is LiCl and water exothermic?
Because the Li+ ion is smaller than the Na+ ion, the Coulombic attractions between ions in LiCl are stronger than in NaCl. However, the dissolution of LiCl in water is an exothermic process.

Which of the following happens when LiBr dissolves in water?
Lithium bromide dissolves in water to form lithium ions and bromide ions: LiBr(s) –H2O–> Li^+(aq) + Br^-(aq) Each ion is surrounded by a “hydration sphere”, that is, a number of polar water molecules which are attracted to the charged ions.
Is Na3PO4 soluble in water?
Is Na3PO4 (Sodium phosphate) soluble or insoluble in water? The answer is that it is soluble in water.
