Chemistry Lesson: Steemit Edition Problem Set 5
1.) What ions form when the following acids/bases/salts are dissolved into H2O? Also is the
compound an acid, base or salt?
a. HI H+ + I- Releases a proton so it’s an acid
b. Rb(Cl)2 Rb2+ + 2 Cl- Just a salt ( there is more to it, but not for now!)
c. Zn(OH)2 Zn2+ + 2OH- Generates hydroxide ions so it’s a Base
d. NH4 H+ + NH3 Releases a proton so it’s an acid (this one is ammonium which is the
acid form of ammonia)
2.) What are the products when we react (just the first protonation of) Phosphoric Acid (H3PO4)
with hydroxylapatite (Ca5(PO4)3(OH) )
H3PO4 + Ca5(PO4)3(OH) H2O + 5 Ca2+ + 3 PO4-2 + H2PO4Interesting side note, this reaction occurs with your teeth when you drink acidic sodas, you
break down the hydroxylapatite in your teeth into these ions which get washed away!
