Answer:
pH of the buffer solution is 1.76
Explanation:
To find the pH of a buffer we can use Henderson-Hasselbalch equation:
pH = pKa + log [A⁻] / [HA]
<em>Where pKa is -log Ka= 1.77 And [A⁻] is molar concentration of conjugate base, NaHSO₃ and [HA] molar concentration of weak acid, H₂SO₃</em>
<em />
Replacing values of the problem:
pH = 1.77 + log [0.304M] / [0.310M]
pH = 1.76
<h3>pH of the buffer solution is 1.76</h3>
Answer:
A paste made of baking soda and water can help neutralize bee venom to reduce pain, itching, and swelling. Apply a thick layer of baking soda paste to the affected area. Cover the paste with a bandage. Leave on for at least 15 minutes and re-apply as needed.
Explanation:
Description in biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
