What does alka seltzer do?
How does it work?
Alka Seltzer relieves stomach aches.
It does this by neutralization--adding a base to an acid to make it more neutral.
500
Dissolves by ionization
What is an acid?
500
RELATE H3O+ TO ACID STRENGTH AND PH.
***I WOULD PRACTICE THIS.
If you increase H3O+, the acid strength will increase and the pH value will go down.

MARINE BIOLOGIST: You are taking a fifth grade class on a field trip to tour your job. You work in a wildlife aquarium with all sorts of sea urchins. Even though the teacher seems to be watching, he is also in awe of what you do every day. You get carried away talking about the cool things that star fish do while one of the fifth graders decided to wade into the sea urchins tank. He starts screaming. You run over and realize that HE’S BEEN STUNG! You learned in graduate school that sea urchins produce lots of hydronium ions. Uh oh! It’s up to you to save the day!
How would you solve this problem?
