Acid and Base 5/13/11 warm-up What are the 3 definitions of Acid and base?

Arrhenius definition acid- hydrogen containing compounds that ionize to yield H + ions base – compounds that ionize to produce hydroxide or OH - ions list examples of each of these monoprotic – diprotic - triprotic - HCl, HBr, HI, HF, HNO 3, HNO 2 H 2 SO 4, H 2 SO 3, H 2 CO 3 H 3 PO 4 H 3 PO 3

Bronsted-Lowry def acid- hydrogen ion donor base – hydrogen ion acceptor conjugate acid-base pair conjugate acid – particle formed when base gains H + conjugate base – particle formed when acid has donated (loses) H +

Conjugate acid and base pairs NH 3(aq) + H 2 O (l)  NH 4 + (aq) + OH - (aq) NH 3(aq) + H 2 O (l)  NH 4 + (aq) + OH - (aq) base acid base acid H 2 O (l)  H 3 O + (aq) + Cl - (aq) HCl (g) + H 2 O (l)  H 3 O + (aq) + Cl - (aq) Conjugate base Conjugate acid

K now Write down in a list all the things you know about Acids and Bases. Quiz this Thursday Test Next Tuesday 5/24 on Acids and Bases. 2 labs this week. Titration and indicator lab Next up Gas Laws Test the next Thursday 5/26

K now Corrosive H in the beginning how to name them sour taste gastric acid-stomach acid – HCl battery acid – H 2 SO 4 aqueous solutions pH scale act as electrolytes

W ant to know 3 definitions of acids? what are pH of acids? uses of acids Why is H 2 O amphoteric? indicators how do we know strength? difference between strength and concentration what does pH stand for?

L earned H 2 O is amphoteric H 2 O is amphoteric
