A saturated solution is when there is a dynamic equilibrium between the solute dissolved, the dissociated ions, the undissolved and the compound in the solution. The concentration of a solution that is saturated is equal to the solubility of the solute in solvent at a certain temperature since solubility is the maximum amount of solute that can be dissolved in the solvent to form a solution. For this case, the solubility of barium nitrate is 130.5 g per liter. To determine the moles of barium nitrate, we do as follows:
130.5 g / L = x g / 4.0 L where x is the mass of barium nitrate in the solution.
x = 522 g Ba(NO3)2
522g Ba(NO3)2 ( 1 mol / 261.34 g ) = 2.00 moles Ba(NO3)2

Cl3C ---Oh products do you expect from the reaction, after acidifying the reaction mixture.
What is acidifying?
Lowering a sample's pH below 2.0 by adding an acid (often nitric or sulfuric). A sample is fixed by acidification in order to prevent change until it is analysed.
Therefore,

Answer:
Intensive and extensive properties are both physical properties. However, intensive properties dont depend on the amount of matter present in a sample, whereas extensive properties do. Intensive properties only depend on the type of matter, such as color, temperature, or solubility. Extensive properties depend on the amount of matter, such as mass, volume or energy
