WebNov 20, 2024 · For a 7.96×10-2 M solution of H2Se, calculate both the pH and the Se2- ion concentration. H2Se + H2O H3O+ + HSe- Ka1 = 1.3×10-4 HSe- + H2O H3O+ + Se2- Ka2 = 1.0×10-11 pH = [Se2-] = M Posted one year ago Q: Transcribed image text : … WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.
WebHuman blood has a pH of approximately 7.4 due to the carbonic acid/bicarbonate ion (H2CO3/HCO3−) buffer system. Any pH changes below 6.8 or above 7.8 can lead to death! Carbonic acid dissociates to form water and carbon dioxide in the equilibrium shown below. This process is crucial in respiration.

WebJul 31, 2015 · HBrO2 is the stronger acid. Explanation: For oxyacids with the same central atom, the acidity increases as the number of atoms bonded to the central atom increases. Thus, we predict that HBrO2 should be a stronger acid than HBrO. This is confirmed by their Ka values . HBrO2 has Ka = 1.2 ×10−5, while HBrO has Ka = 2 ×10−9. Answer link WebThe pH of a solution of H2Se with a concentration of 0.38 is 4.94. What is pH? The pH of a solution can be calculated using the formula: pH = -log[H+] where [H+] is the concentration of hydrogen ions in the solution. For a solution of H2Se, we first need to determine the concentration of hydrogen ions (H+).
