Homework Help: Chemistry

Posted by Nia on Monday, October 17, 2011 at 11:12pm.

Assuming equal concentrations , rank these solutions by pH. RbOH(aq), NH3(aq), HF(aq) HBr(aq), Ca(OH)2(aq).

I know the most acidic solution has the lowest pH and the most basic solution has the highest pH. But how am i supposed to know the pH if i don't know the concentration of each solution?
