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 pH=2, what is the pOH? Is it acidic or basic?

pOH= 12, acidic

What is the pH range for basic solutions?

pH > 7

If pOH= 4, what is the pH? Is it acidic or basic?

pH= 10, Acidic

If you have blue litmus paper in the presence of an acid, it turns what color?

RED

Label the acid and base for the reaction: HC2H3O2 + H2O ----> H3O+ + C2H3O2-

HC2H3O2= Acid, H2O= Base

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

Calculate the pH of a 1x10-2 M solution of HF.

pH=2, Acidic

Complete the net ionic equation: HCl ---->

HCl ----> H+ (aq) + Cl- (aq)

Calculate the pH of a 1x10-9 M solution of NaOH.

pH=9, Basic

What is the pH range for neutral solutions?

pH= 7

If pH= 10, what is the pOH? Is it acidic or basic?

pOH= 4, Basic

Label the acid and base for the reaction: H2SO4 + NH3 ----> HSO4- + NH4+

H2SO4= Acid, NH3= Base

Complete the net ionic equation: NaOH ---->

NaOH ----> Na+ (aq) + OH- (aq)

If pH= 7, what is the pOH? Is it acidic or basic?

pOH= 7, Neutral

What kind of acid/base dissociates completely? (strong or weak?)

STRONG

If pOH= 6, what is the pH? Is it acidic or basic?

pH= 8, Basic

If pOH= 7, what is the pH? Is it acidic or basic?

pH= 7, Neutral

Calculate the pH of a 1x10-3 M solution of HCl. Acidic or Basic?

pH= 3, Acidic

Complete the net ionic equation: KOH ---->

KOH ----> K+ (aq) + OH- (aq)

What is the pH range for acidic solutions?

pH < 7

If you have red litmus paper in the presence of a base, it turns what color?

BLUE

Label the acid and base for the reaction: NaHCO3 + HCl ----> NaCl + H2CO3

NaHCO3= Base, HCl= Acid
