When we mix 25.0 mL, 2.0 M BaCl2 with 25.0 mL, 3.0 M Na2SO4 what is the balanced equation? What is the ionic equation? what is the net ionic equation?
BaCl2 + Na2SO4 ---> BaSO4 + 2NaCl
Ba++ + 2Cl- +2Na+ + SO4-- --> BaSO4 + 2 Na+ + 2Cl-
Na+ and Cl- same both sides so
net:
Ba++ + SO4-- ---> BaSO4
Thanks man both answers you have answered for me have checked out to mine that i have got.
To determine the balanced equation, ionic equation, and net ionic equation for the reaction between 25.0 mL of 2.0 M BaCl2 and 25.0 mL of 3.0 M Na2SO4, you need to first identify the reactants and their respective ions.
The reactants in the reaction are BaCl2 and Na2SO4.
1. Balanced Equation:
The balanced equation represents the overall reaction, showing the reactants and products in their molecular or formula units. To determine the balanced equation, you need to combine the ions of the reactants and ensure a balanced number of each atom:
BaCl2 + Na2SO4 → BaSO4 + 2NaCl
2. Ionic Equation:
The ionic equation represents the reaction in terms of separate ions rather than complete compounds. Start by dissociating the reactants into their respective ions:
Ba2+ + 2Cl- + 2Na+ + SO42- → BaSO4 + 2Na+ + 2Cl-
3. Net Ionic Equation:
The net ionic equation includes only the species involved in the reaction and excludes the spectator ions. Spectator ions are ions that appear on both sides of the equation and do not participate in the actual reaction.
In this case, the Na+ and Cl- ions are spectator ions because they appear on both sides of the equation. Thus, they can be removed from the equation:
Ba2+ + SO42- → BaSO4
Therefore, the net ionic equation for the reaction is Ba2+ + SO42- → BaSO4. This equation shows the active participants and represents the essential chemical change occurring in the reaction.
Remember that before writing the final equations, you need to ensure the stoichiometry of the reactants. In this case, both the BaCl2 and Na2SO4 concentrations are given, so you also need to account for the volume and convert the mL to liters to determine the amount of substance used in the reaction.
