Acids and Bases Flashcards
(23 cards)
taste
acid: sour
base: bitter
texture
acid: watery
base: slippery
electrical conductivity in aqueous solution
both conduct
ph
acid: less than 7
base: more than 7
ion responsible for properties
acid: H+
base: OH-
indicator colours
litmus:
acid: blue turns red
base: red turns blue
phenothalein:
acid: colourless
base: fuschia
corrosion
both are corrosive
rxn w/ metals
acid: rxn to form H2 gas
base: doesnt react
rxn w/ carbonates
acid: rxn to form CO2 gas
base: no rxn but some dissolve
examples
acid: lemon juice
base: bleach
order of examples
stomach acid
lemon juice
vingegar
soda
coffee
milk
water
baking soda
lava soap
ammonia
oven cleaner
pH scale
pH stands for power of hydrogen
used to desc the acidity or basicity of a solution based on the concentration of H ions in solution
dissociation
ionic bond in cmpd breaks apart
ionization
colvalent bond breaks and ions form then disociate
acids
ionizes in water to prod one or more H ions
bases
dissasociates in water to form one or more OH ions
hydrochloric acid
hcl
sulfuric acid
h2so4
sodium hydroxide
naoh
titration
a lab procedure that involves carefully measuring and adding of known concentration solution of a base/acid from a burette into a measured volume of an unknown concentration solution of a base/acid
- used to determine concentration
acid base titration
quantitaive procedure that provides a means to determins the point of neutralization of an acid/base solution
titrant
solution in the burette during a titration
end point
tutrated or experimentally determined point of neutralization
- sharp colour change in a property occurs
