high, low
100
What is the difference between a solute and solvent?
solute is being dissolved, solvent is doing the dissolving
100
What is energy?
the ability to do work
100
What ion do acids produce in solution?
hydrogen (H+)
100
Why do we perform titrations?
to use an acid or base of known concentration to find the concentration of an unknown acid or base
200
What is one device used to measure the pressure of a gas?
barometer, manometer
200
What is an immiscible solution? Give an example.
two substances that will not mix-oil and water
200
What are the two most common units used to measure heat?
Joule and calorie
200
What ion do bases produce in solution?
hydroxide ions (OH-)
200
Which solution goes in the buret and which goes in the erlenmeyer flask?
known solution goes in the buret and unkown goes in the flask
300
WHY does an increase in temperature result in an increase in pressure of a gas (at fixed volume)?
increased temperature causes particles to move more quickly, bumping into each other more frequently, and raising pressure
300
What is the general rule for if something will dissolve in something else?
like dissolves like
300
What is the device used to measure the transfer of heat?
calorimeter
300
Which equation do you use to find pH if you know the hydrogen ion concentration?
ph=-log[H+]
300
What are always the products of an acid-base reaction?
a salt and water
400
How are volume and pressure related in a gas?
inversely
400
Name 3 factors that affect solvation and explain how.
stirring, temperature, and surface area-all increase solvation
400
What equation do you use to measure a change in energy?
q= m x C x deltaT
400
How would you find the hydroxide ion concentration if given the pOH?
[OH-]=10^-pOH
400
Which solution is not a strong base? NaOH, KOH, CaOH, BaOH
CaOH
500
How are volume and temperature, and pressure and temperature related in a gas?
directly
500
Describe what happens when an ionic compound is dissolved in water vs. when a covalent compound is dissolved.
when ionic is dissolved it dissociates into ions, but when a covalent is dissolved it separates into whole molecules
500
Explain all the variables used in the change in enthalpy equation
q-heat m-mass C-specific heat deltaT- final temperature minus initial temperature
500
What does amphoteric mean?
a compound that can act as an acid or base
