Calculate the pH of a 1x10-3 M solution of HCl. Acidic or Basic?
pH= 3, Acidic
Calculate the pH of a 1x10-9 M solution of NaOH.
pH=9, Basic
Calculate the pH of a 1x10-2 M solution of HF.
pH=2, Acidic
Label the acid and base for the reaction: H2SO4 + NH3 ----> HSO4- + NH4+
H2SO4= Acid, NH3= Base
Label the acid and base for the reaction: HC2H3O2 + H2O ----> H3O+ + C2H3O2-
HC2H3O2= Acid, H2O= Base
Label the acid and base for the reaction: NaHCO3 + HCl ----> NaCl + H2CO3
NaHCO3= Base, HCl= Acid
What kind of acid/base dissociates completely? (strong or weak?)
STRONG
Complete the net ionic equation: HCl ---->
HCl ----> H+ (aq) + Cl- (aq)
Complete the net ionic equation: NaOH ---->
NaOH ----> Na+ (aq) + OH- (aq)
Complete the net ionic equation: KOH ---->
KOH ----> K+ (aq) + OH- (aq)
Which of the following are acids? lemon, lime, milk, eggs, water, stomach acid
lemon, lime, water, stomach acid
Which of the following are bases? grapes, milk, eggs, water, bleach, soap, ammonia
water, bleach, soap, ammonia
If you have blue litmus paper in the presence of an acid, it turns what color?
RED
If you have red litmus paper in the presence of a base, it turns what color?
BLUE
Water is known as amphoteric, which means it can act as an acid or a base. How does this work?
H2O + Acid: H2O= Base, H2O + Base: H2O=Acid
What is the pH range for acidic solutions?
pH < 7
