Chapter 15 Flashcards
Substance that is dissolved
Solute
Substance that does the dissolving
Solvent
A homogeneous mixture of two or more substances in single physical state
Solution
It means same composition all the way through
Homogenous
Two or more substances not bonded together
Mixture
What are the three physical states
So.id liquid and gas
Solutions are generally…..
Transparent
Solute particles are ….
Ions or molecules
Solutions don’t……. When left standing
Seperate
Amount of solute in a given amount of solvent or solution
Concentration
Little bit of solute compared to amount of solvent
Dilute
Concentration is described in two ways…
Qualitatively
Quantititatively
Comparing amounts without being exact
Qualitative concentration
Lots of solute compared to amount of solvent
Concentrated
It’s an exact measurement of the amount of solute and solvent
Quantitative concentration
Quantitative concentration is expressed in two ways
Molarity (M)
molality (m)
It’s the number of moles of a solute per liter of solution
Molarity
m = ….
mol
m = ——
L
Molality M ==
Liters of solution
its the process of an ionic compound breaking into single ions -
dissociation
hydronium ion -
H3O
how does a hydronium ion form -
put acid in water
acid dissociates
H+ adds to water molecule
Acids taste …
sour
Bases taste …
bitter
Acids feel …
sticky
Bases feel..
slippery
Acids reaction w a metal …
strong reaction
makes H2
bases reaction w/ a metal …
weak reaction
do acids conduct electrical .
yes
do bases conduct electrical
no
examles of acids …
vinegar, pop, yogurt
examples of bases ..
bleach, soap, baking soda
acids produce what kind of ions ..
H+
bases produce what kind of ion ..
OH -
naming bases ….
no name change needed
naming acids ….
look @ ending (ate, ite, ide)
it is a special version of a double - displacement reaction
neutralization reaction
it is a number on a scale
scale is various colors
it measures acid
pH
pH tells us the …..of …….. in the solution
concentration
hydronium ions
pH only goesup tp …
14
pH higher than 7 …..
a base
pH lower than 7 …..
a acid
water is a pH …
