H2se ph
Did you know?
Webaryast The 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+).

WebAcid(a): H2 S Acid (b): H2Se Because these are in/with the greater the the weaker the bond to H. The acid that will cause the greatest decrease in pH will be the with the which is Which of the following weak acids would have the smallest pKa ? Acid (a): H2 S Acid (b): H3P Because these are in/with , the greater the the weaker the bond to H. WebDec 8, 2014 · But then you have to know what pH means. So we'd class H 2 Se as a weakish acid a bit more acidic than acetic. H 2 Te is getting to be strongish. This may be the first and last time you meet it. And even H 2 Se not often.
