acids
what does the ending -ate change to
-ic
What is a base?
any substance generating OH- ions when dissolved in water.
What does a pH 1-6 indicate
acid
what is a buffer
it resists pH change when added to acids or bases
What is a well known acid
aspirin, glycine, citric acid, or sulfuric acid
What are some major properties of bases
taste bitter and chalky, feel soapy and slippery, pH greater than 7
what do we use to calculate pH
molarity (m=Moles/L)
hydrochloric acid (HCl) is which of the following
-weak acid -weak base -strong acid -strong base
strong acid
what is an acid might you use at home
vinegar, lemon juice, battery acid, carbonated sda
What is a well known weak base
caffeine
What is one thing used to test pH
litmus paper
Ph paper or meter
universal indicator
natural indicators
name the following acid H2S
hydrosulfuric acid
what are amino acids
They are molecules that add to each other to make polypeptides which make proteins. They break down food.
what are the strong bases we discussed in class
NaOH, KoH, Ba(OH)2, NA3, PO4
concentration of 1.0 X 10-3M
ph= 3
poH= 11
OH-1=1.0 X 10-11
which base is stronger: KOH or Al(OH)3
KOH
What is the reaction for nitric or sulfuric acidic rain
Sulfuric: SO3 + H2O = H2SO4
Nitric: NOx + H20 = HNO3
what is the difference between a strong and weak bases
Strength based on ionization. Weak bases don't break down in water, strong ones fully break apart in water
100 g of HCl is dissolved into 2.0 liters of water, what is the molarity of the solution?
1.4 m/L
what is the reaction between hydrochloric acid and sodium hydroxide?
HCl+NaOH---->NACl
