Interpretation:
To determine when writing the chemical equation for a reaction, how do you indicate that a given reactant is dissolve in water and formed a precipitate.
Concept Introduction:
A balanced chemical equation is an equation that contains same number of atoms as well as of each element of reactants and products of reaction.
For example, the reaction between lead sulphide and oxygen is as follows:
In the given reaction, the number of all atoms, on the both side are equal hence this is a balance reaction.
The most common driving forces which create product in
- Formation of a solid.
- Formation of water.
- Transfer of electrons.
- Formation of gas.
If a substance is not soluble in water than it forms precipitate. The phase of the precipitate is solid. The precipitates are formed depending on the solubility of salt in water.

- Apply Students conducted a lab to investigate limiting and excess reactants. The students added different volumes of sodium phosphate solution (Na3PO4) to a beaker. They then added a constant volume of cobalt(ll) nitrate solution (CO(NO3)2) stirred the contents, and allowed the beakers to sit overnight. The next day, each beaker had a purple precipitate at the bottom. The students decanted the supernatant from each beaker, divided it into two samples, and added one drop Of sodium phosphate solution to one sample and one drop of cobalt(ll) nitrate solution to the second sample. Their results are shown in Table 11.5. a. Write a balanced chemical equation for the reaction. b. Based on the results, identify the limiting reactant and the excess reactant for each trial.arrow_forwarduppose you are trying to help your friend understand the general solubility rules for ionic substances in water.
