AI Thread Summary
The discussion centers on designing an experiment to test the effectiveness of various antacids in neutralizing hydrochloric acid (HCl). The user is unsure about the procedure, particularly regarding titration and measuring solid antacids. Suggestions include measuring the mass of the antacid tablet, using water to dissolve it, and employing an indicator to determine when neutralization occurs. Additionally, it is recommended to add excess HCl to the antacid and titrate the remaining acid with a base like NaOH. The user expresses gratitude for the guidance and feels more confident about proceeding with the experiment.

I have to design and conduct an experiment to test the effectiveness of 4 different kinds of antacids on neutralizing HCl (stomach acid).

I could do this if you gave me the procedure but I have to completely design an experiment.
I suck at chemistry and this is all going over my head.
I was thinking about doing something with titrations but I don't know exactly how to go about that.

Would I put the antacid is a flask, and then titrate it with HCl?

Someone PLEASE help me.
Clearly, chemistry is not my thing.

Okay what I have so far is:
You put the acid in the burette(?)
base (antacid) in the flask.

VolumeXConcentration of HCl / Volume of antacid = Concentration of the antacid

1-how do you measure the volume of a solid antacid?
2-how do you know how much HCl has been neutralized?

I have to figure this out in 2 days.
HELP ME PLEASE.
 
You have the right idea. You would most likely measure the mass (not volume) of the antacid tablet. Try using some fraction of the sample size recommended by antacid instructions. What pH will you get after the neutralizing ability of the antacid tablet has been exhausted? How might you measure this pH?
 
wouldnt you put an indicator in the flask so you know when its been neutralized

but if I have a solid antacid, how would I do that?
Would I add water to the antacid and then put indicator in it?
 
You are better at this than you think...
 
lol
thanks
ive been looking all over the internet trying to figure it out

so adding water to the antacid wouldn't mess it up or anything would it?
 
No. You could also add acid (measured amount) in excess to the antacid tablet and titrate the excess acid with a base titrant (NaOH, 0.1N). How much excess acid to add would be something for you to figure out after a few preliminary tests with indicator solution. Use this method if the tablet dissolves slowly or not at all. Calcium carbonate could be a component, for example, and will not dissolve in the water you add.
 
I think tums is calcium carbonate.
Im pretty sure I've figured out exactly what I am going to do.
THANK YOU :D
