What is the hydrogen ion (H+) concentration of a solution of pH 8?
fgiga [73]

Answer:

10−8 M.

Explanation:

In this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation, pH = − log [H+] , we can solve for [H+] as,

− pH = log [H+] ,

[H+] = 10−pH,

by exponentiating both sides with base 10 to "undo" the common logarithm. The hydrogen ion concentration of blood with pH 7.4 is,

[H+] = 10−7.4 ≈ 0.0000040 = 4.0 × In this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation, pH = − log [H+] , we can solve for [H+] as,

− pH = log [H+] ,

[H+] = 10−pH,

by exponentiating both sides with base 10 to "undo" the common logarithm. The hydrogen ion concentration of blood with pH 7.4 is,

[H+] = 10−7.4 ≈ 0.0000040 = 4.0 × 10−8 M.

Why is a saturated NaCl solution an example of an equilibrium system? A. Because of the reversible nature of solidifying and mel
nataly862011 [7]

Answer:

Option B, Because of the reversible nature of crystallizing and dissolving

Explanation:

Solution containing the maximum amount of solute that can be dissolved in the given solvent at the particular temperature is called saturated solution.

Reversible reaction is the reaction which can go in reverse and forward direction both on varying reaction condition.

In the saturated NaCl solution, on lowering temperature, The the dissolved NaCl molecules may crystallize. Likewise on increasing temperature, the crystallized crystals may dissolved. As the reaction moves in both the direction, therefore its considered to be equilibrium system.

Therefore, amog given, option B is correct.

Because of the reversible nature of crystallizing and dissolving
