Calculate the hydrogen ion concentration in the following biological fluids whose pH are given below:

The ions having same number of electrons are called isoelectronic ions. The above order is due to increasing order of effective nuclear charge.

pH = – log[3.8 × 10–3 ]  = – {log[3.8] + log[10–3 ]}  = – {(0.58) + (– 3.0)}  = – {– 2.42} = 2.42  Therefore, the pH of the soft drink is 2.42...

Solution: Significance of sodium and potassium in biological fluids: K+ and Na+ cations are present in the red blood cells. The ratio of K+ to Na+ ions in mammals such as human beings, rabbits, rats and horses is 7:1.

(c) Gases and liquids behave like fluids

When a body moves through a fluid, it experiences an opposing force which tries to oppose its motion through the fluid. This opposing force is known as the drag force....

(a), (b) and (d) are metals. (a) Magnesium (b) Sodium (d) Lithium

(i) If H+ ion concentration is more, pH will be less and vice-versa or pH of a solution is inversely proportional to H+ ion concentration or pH 5.2 log (H+). (ii)...

It is of which chapter

The correct answer is (b) uA > uB
