I need 0.5mol/L of the following HCl (lemon juice), NaOH(Drain Clearner), Acetic acid(vinegar) and sodium bicarbonate(baking soda). The problem is I don't know what the concentration of HCl is in lemon juice. Same thing for the other three items. How would I do this?

In addition to agreeing with the previous answer (especially the part about the NaOH) I don't think this can be done.
0.5M Acetic acid is significantly stronger than household vinegar, so how are you expected to get the concentration to .5M even if you know the starting concentration?

Actually, if your teacher gave you this assignment, you can tell him or her, that this is ridiculous. First of all, the acid in lemon juice is citric acid, not HCl. Thank goodness for that. It is true that vinegar is acetic acid, baking soda is sodium bicarb, and drain cleaner does contain NaOH, but to get 0.5M of any of these, is borderline idiotic. I know you wanted a more scientific answer, but aside from measuring the pH of these, and then doing some deductive reasoning, you can't do it.
