+ Bronsted-Lowry Acids and Bases
1. Bronsted Acids are ___________________ donors and bases are ____________________ acceptors.
H2O + NH3 ⇒ NH4+ + OH–
+MAD Skillz: Identify the acid and base in a Bronsted acid-base reaction 1) Find a match in the reaction
2) Determine if the molecule in the reactants gained or lost an H
3) Draw an arrow of where the H goes in the reaction4) The acid loses and the base gains the H+
HCl + NH3 ⇒ NH4+ + Cl– (aq)
B/L acid = ________ B/L base= ________

3) Draw an arrow of where the H goes in the reaction4) The acid loses and the base gains the H+
H2O + H2S ⇒ HS–+ H3O+
B/L acid = ________ B/L base= ________
+2. Arrhenius: Acids are
___________________ donors and bases are ____________________ donors.
H2Mg + LiOH Li2Mg + H2O
Arrhenius Acids and Bases
+MAD Skillz: Identify the acid and base in an Arrhenius acid-base reaction 1) Determine if the reaction is Arrhenius (has H2O in
products) 2) The reactant with the -OH is the base3) The reactant with the H+ is the acid
Label the acids (A) and bases (B) in the reactions below
HCl (aq) + NaOH (aq) ⇒ H2O (l) + NaCl (aq)

products) 2) The reactant with the -OH is the base3) The reactant with the H+ is the acid
Label the acids (A) and bases (B) in the reactions below
HBr (aq) + RbOH (aq) ⇒ RbBr (aq)+ H2O (l)
+3. Acid Base neutralization is a
___________________ ___________________ reaction.
4. Acid Base Neutralizations always create ____________________ and a _______________________
Acid Base Neutralization
+MAD Skillz Predict the products of an Arrhenius acid-base reaction reaction 1) Put H2O in the reactants
2) Cross out the H and the OH in the reactants3) Combine the remaining ions of the reactants to create
the salt
Predict the products
a. NaOH + HF ⇒ ________ + ________
