________________________ Memorize polyatomic ions before Friday.
We should have time to talk about the exam, bring questions. Definitely study Ch. 5 and finish homework ASAP.
Use end of chapter questions and answers in back of book to
quiz yourself on naming (without notes). Review session Sunday (enter through 3rd floor doors). I will post
on ICON. 7 9/10/2013 Chemical Properties of Acids Chapter 5C - Atoms and
Elements Acids are molecular compounds, BUT when dissolved in
water, acids tend to dissociate (fall apart) and form H+ ions
and anions (similar to ionic compounds.) Naming acids Some other properties of acids:
•Dissolve many metals
•such as Zn, Fe, Mg; but not
Au, Ag, Pt
•React with bases Binary acids Oxyacids Exam information
Question/answer if time permits Categories of Acids
• Binary acids have H+
• cation and nonmetal
