Re: J.7

Since this is a neutralization problem, your products are water and whatever they give you; now, you need to figure out what its reactants are from those. So, for A, you see that KBr and H2O are the products. So, the reactants must be KOH (base) and HBr (acid). This combination of H+ ions and OH- i...

Stronger acid?

Which would be the stronger acid HClO or HClO2? I know that you first look at bond length and then anion strength but how would you figure this one out?

I get that for a conjugate acid you add an H and add + to overall charge. But, for part a), would you add the H to the H of CH3 or the H of NH2?
