In a 0.1 M solution of glycine at pH 9.0, what fraction of glycine has its amino group in the —NH + 3 —NH3+ form? I know the answer, but can someone explain why the fraction is .25/(1+.25)) x100% = 20%? Where did the (1+.25) come from?
In a 0.1 M solution of glycine at pH 9.0, what fraction of glycine has its amino group in the -NH3+ form? I can't figure out how to get from 0.25=[NH2]/[NH3] to (0.25/[0.25+1]) x 100 = 20% Why do you divide by (0.25+1) ?
