-Bronsted-Lowry base accepts a proton (H+).-C8H10N4O2 accepts a proton from H2O to kind HC8H10N4O2+ .C8H10N4O2 (aq) + H2O--> HC8H10N4O2+ (aq) + OH- (aq)
.1. Include H+ to type the conjugate acid. + =2. Eliminate H+ to form the conjugate basic . = + Note: is AMPHIPROTIC: act as a Brønsted-Lowry acid/base.
When no other substances are dissolved in water, what have to be true around the concentrations of and also created by this reaction?
The hydroxide ion concentration in one (aq)solution at 25°C is 8.9×10-2 M.The hydronium ion concentration is M...The pH that this systems is...The pOH is...
