Title: Bases + Acids
Post by: SorchaMM on April 08, 2005, 01:15:50 AM

I asked this earlier about types of bases, but I'm also confused about bases and acids reacting:

a. Calcium hydroxide solution with acetic acid
so Ca(OH)₂ + CH₃COOH yields ???

I know I get H₃O⁺ + CH₃COO^- when Im mixing acetic acid with water, right? But then with calcium hydroxide, how do I know what decides to combine with what? I don't even know if I'm setting it up right.
Is water a by product? or.... ?

Ca(OH)₂ + 2 CH₃COOH --> (CH₃COO)₂Ca + 2H₂O

Calcium cation reacts with acetate anion.
H⁺ reacts with OH^-

You can of course make your equations longer, writing the hydrolisis of CH₃COOH to get the H₃O⁺.

Really, it's in the books.

Look for neutralization reaction between acid and base.

Calcium cation reacts with acetate anion.

Some complexation is possible, but in general they are just spectator ions.

Yeah, well the general idea is H+ + OH- = H2O
