Question
Please give a brief explanation, thanks.
1. The following system refers to a acid-base indicator. Let's say we start with a neutral solution that is orange. Hln(aq) Red arrow ln^- Yellow + H^+(aq) (a) What color will the solution become when HCI (H^+ and Cl^-) is added? Explain. (b) In which direction will the reaction shin when NaOH (Na^+ and OH^-) is added? Explain. One of the most important buffer systems in our blood is the bicarbonate system shown below. Acidosis results from an increased [H^+] while alkalosis results from a decreased [H^+]. HCO3^-(aq) + H^+(aq) arrow H2O(l) + CO2(g) (a) Does a person get acidosis when he holds his breath? Explain. (b) Why does breathing into a paper bag help to reverse the effects of hyperventilation? Explain.Explanation / Answer
1.
a) When HCl is added the concentration of H+ increases which pusehe the equilibrium of the given indicator eaction towards left. So the colour changes to red
b) When NaOH is added the H+ produced by the indicator are consumed by the OH- produced by NaOH. So the eqilibrium is shifted forward (right)

When a person hyperventilate it cause the person to hold respiratory alkalosis . Hyperventilation causes increased CO2 excretion. Leading to decrease carbonic acid and result surrounded by alkalosis .
When the person hold their breath they develop respiratory acidosis . CO2 is retained when you hypoventilate , the carbonic acerbic accumulates surrounded by the blood causing H to be released bringing down blood pH. When a person holds their breath, carbon dioxide (a by product of run of the mill cell metabolism) builds up in the blood. There is an enzyme , carbonic anhydrase, that speeds up the combination of carbon dioxide and river (from the blood plasma) into carbonic acid. This watery acid readily dissociates within water (i.e., the blood plasma) into bicarbonate and hydrogen ion. Since pH is defined as the cynical log of the hydrogen ion concentration ion, as H+ increases, the pH decreases.
The disparate reaction occur during hyperventilation . Hyperventilation is defined as an increase in the amount of fresh nouns in the alveoli per element time. While very little extra oxygen is taken contained by (because the blood is approximately 98% saturated near oxygen during normal breathing), much more carbon dioxide is blown stale than usual. Thus, the equation is driven in the converse direction, and H+ ions are removed from the blood, causing an increase surrounded by the pH.The easiest road to think of it is to remember that CO2 is an sharp, so if you have extra CO2 (hypoventilation), you'll be acidotic, and vice-versa.
