Multiple Choice Equation
« on: April 16, 2007, 11:07:17 PM »
What can be said about the equation?

HNO2(aq) + H2O(l) ? H3O+(aq) + NO2-(aq)
 
a) Many H3O+ ions form.  
b) HNO2 is a weaker acid than H3O+.  
c)The reaction will form many products.  
d) All of these are true statements.  

So here's my attempt...  

Not many H3O+ ions form b/c H30 is a stronger acid than HNO2 {which would eliminate a) and b)
Because a weaker acid dissociates incompletely meaning more ions will remain on the products side.  So from this it is b)  

Am i correct in all my assumptions and throught my thought proccess?

Any help appreciated thanks.

If many H30 molecules were formed, products would be favored.  Acid/base reactions go from stronger to weaker, so from the question and choices, you should be able to figure out the answer.  I can't understand exactly what you typed out, if you could make it a bit clearer I could try to help you out more.

Yes, HNO2 is a much weaker acid than H3O+
