Briefly explain with equations how antacids work? 
e.g: Tums

anonymous · Answer

all i know about antacids is, they try to balance acidity in stomach..maintaining a specific pH...specifically on empty stomach, acids are produced in excessive amount..which can't be  handled by it..that's where we suffer heatburn...so we take antacids to maintain normal pH level....Did you google it?

yh but wasn't successful in finding the answer, and also i need some equation as i answer this q'.

I don't know, but I have the good idea that it might be a buffer. You know they work right?
If it is not a buffer I gonna do some google search.

frostbite · Answer

how they work right?*

rane · Answer

yh but u have to answer using equations

frostbite · Answer

Well set up some equations with buffer solutions and calculate the pH?

frostbite · Answer

Try look at this system (attachment)
add some HCL: 4,0 ml  0.25 M
calculate the change in pH

after that try do the same, but in water and calculate the change in pH. are they different?

rane · Answer

w8! whts the role of pH here ? werent we were looking for how antacids work?

frostbite · Answer

Yea that is what I say, I believe that antacids are drugs that work as buffers... AKA we look at how buffers work  :)
