For Mass-Balance eqzns, in my text it is described as "relating the equillibrium concentrations of various species in a solution to one another and to the analytical concentrations of the various solutes.
Is the analytical concentration described, the molar concentration??
yes. It's called mass balance but concentration (molarity) is used.
thank you Dr.Bob
You're welcome! I'm glad I could help you. Yes, in the context of mass-balance equations, the term "analytical concentration" refers to the molar concentration of the various solutes in the solution. Molar concentration, also known as molarity, is a measure of the amount of a solute dissolved in a given volume of solution.
To determine the analytical concentration or molarity of a solute, you need to first measure the mass of the solute and the volume of the solution. Then, you can use the formula:
Molarity (M) = moles of solute (mol) / volume of solution (L)
where the moles of solute can be calculated using the mass of the solute and its molar mass. By plugging in the appropriate values, you can determine the molar concentration of the solute.
It's important to note that mass-balance equations are used to establish relationships between equilibrium concentrations of different species in a solution. These equations are based on the principles of conservation of mass, where the total amount of solute before and after a reaction must remain the same. By using the analytical concentrations or molar concentrations of the different solutes, you can solve these mass-balance equations to determine unknown concentrations or to evaluate the progress of a reaction.
I hope this explanation helps! If you have any more questions, feel free to ask.
