experiment done in my lab taking constant voluumes of a unknown substrate,elastase enzyme and increasing concentrations of elastase enzyme inhibitor. A graph between absorbency and enzyme inhibitor concentration revealed the absorbency increased as we increased the enzyme inhibitor concentration. Can i say from the experiment what is the type of inhibition. If not what experiment should be done to find the mode of inhibition of enzyme

I add aqueous AgNO3 to NaOH and a precipitate forms. Then I add nitric acid HNO3 and the precipitate dissolves. How would I write the equation for my reactions. Would this be correct?

AgNO3 (aq) + NaOH (aq) --> AgOH (s) + Na+(aq)

And then...
AgOH (s) + Na (aq) + HNO3 (aq) --> AgNO3 (aq) + H2O (l) or would it instead yield Ag(NH3)2 (aq)??
