7.3 may be treated with an alkali Such as sodium hydrogen and carbonate. Why would this treatment raise the pH of the blood?

Increases in blood pH indicate alkalemia. Increases can be a result of a respiratory (or metabolic) disturbance.

<h3>What causes the pH of the blood to increase?</h3>

Losing too much water from your body can increase blood ph. This happens because you also lose some blood electrolytes — salts and minerals — with water loss. These include sodium and potassium.
The body's pH level is critical to the functioning of the bodies cells. A pH in the range of 7.35 to 7.45 is considered "normal", although a large number of doctors get nervous if the pH is towards the outer edges of that range. If your pH gets down to 6.9, you'll be a coma. At 6.8, you're dead. And if the pH goes up to 7.8, you're also dead.
The hydrogen ion concentrations for pH = 7.35 and pH = 7.45 are 4.46 x 10⁻⁸ M and 3.54 x 10⁻⁸ M respectively.
When the pH of a solution is less than 7, the hydrogen ion concentration is higher and therefore the solution is acidic.
On the other hand, when the pH of a solution is greater than 7, hydroxide ion concentration is higher and the solution acts as a base.
The normal pH range of blood is given as 7.35 - 7.45 which is greater than 7. That means blood is slight basic in nature.
Let us find hydroxide ion concentration of blood.

The hydrogen ion concentration for pH = 7.35 is 4.46 x 10⁻⁸ M

Calculation of [H+] for pH = 7.45

pOH = 6.55

[OH-] = 2.82 x 10⁻⁷

Similarly, for pH = 7.45, we get hydrogen ion concentration of 3.54 x 10⁻⁸ M.
