The inability to regulate the concentration of sodium ions in the blood could be due to the improper functioning of one of the following

Which of the following hormone/enzyme is/are correctly paired with its function? I. Renin - Enzyme that catalyses the formation of angiotensin I. II. Aldosterone - Regulate water reabsorption at the distal convoluted tubule. III. Antidiuretic hormone -It is a powerful vasoconstrictor that stimulates the secretion of aldosterone. IV. Angiotensin II - Promotes reabsorption of sodium at distal convoluted tubule.

How is the concentration of hydroxide ions (OH -) affected when excess base is dissolved in a solution of sodium hydroxide ?

25.3 of sodium carbonate , Na_2CO_3 is dissolved in enough water to make 250 ml of solution. If sodium carbonate dissociates completely molar concentration of sodium ion, Na^+ and carbonate ions, CO_3^(2-) are respectively (Molar mass of Na_2CO_3=106 g mol^(-1) ).

Assertion (A) : In sodium chloride crystal, Na^(o+) ions occupy OVs while Cl^(ɵ) ions occupy vertices of octahedron. Reason (R ) : The radius ratio of Na^(o+) : Cl^(ɵ) lies between 0.4 and 0.7 .

[A] : Most of the solutes in ECF and cytoplasm are electrolytes, i.e., electrically charged par- ticles or ions. Maintenance of an equilibrium between intracellular fluid and ECF is vitally essential for all cells. [R]: This osmotic equilibrium is maintained by sodium and potassium pump of the cells. It operates with the help of a Na^+, K^+ ATP as enzyme located in the cell membrane.
