Answer:

B.) The drug gets carried through a stationary phase by a mobile phase and the retention time identifies the drug.

Explanation:

Chromatography is used in purifying complex mixtures of organic compounds. It uses the adsorption tendencies of compounds to seperate and identify them.

Chromatography is made up of two phases in contact, the stationary phase or non-mobile phase and the mobile phase. The movement of the mobile phase over the stationary phase causes the separation of a mixture into its constituents.

The stationary phase is made up of silica-gel or alumina in a solvent (an adsorbent) and the mobile phase or carrier is the organic solvent which is the drug.

For H3PO4, Ka1 = 7.3 x 10^-3, Ka2 = 6.2 x 10^-6, and Ka3 = 4.8 x 10^-13. A 0.10 M aqueous solution of Na3PO4 therefore would be

Answer:

The aqueous solution of $Na_{3} Po_{4}$ therefore would be "strongly basic."

Explanation:

Strongly basic because the $Na_{3} Po_{4}$ is completely an ionic compound. These compound can be 100% splitted into metal ions and hydroxide ion when used in the aqueous solution. Each moles dissolves which can give rise to mole of hydrogen ions when used in the solution. Whereas strong bases are not soluble in water as well. in the presence of water equilibrium can also be achieved. A strong base has the capability which can just remove the proton from the molecule.

What is an ion-ion intermolecular force?

Dafna1 [17]

Answer: Ion-ion forces, also known as ionic bonding, are the simplest to understand. These forces arise from the electrostatic attraction between two ions with opposite charges.
