Acid bases definitions
100
name 2 properties of an acid and 2 properties of a base
What is acids taste sour and turn litmus paper from blue to red and bases taste bitter and are slippery
100
these are 4 factors that affect reaction rate
What is concentration, temperature, surface area (particle size) and catalyst
100
equation: H2+ I2 <=> 2HI if we add more reactants, will the forward reaction be favored or reverse reaction?
What is the forward reaction (drive the reaction right)
100
this is why salt solutions conduct electricity
What is they are made up of ions which are electrolytes
100
this is the Arrhenius (1st) definition of an acid
What is H+ producer
200
this letter shows a method to decrease reaction rate a) heat up the reactants b) use a higher concentration c) increase the volume of the reaction container (for gases) d) add a catalyst
What is C) if you increase the volume, you are basically decreasing concetration
200
3H2 (g) + N2(g) <-> 2NH3(g) this is the direction equilibrium will shift if volume is increased
What is volume increases so pressure decreases and shifts to the side with more moles of gas. shifts right
200
this is the product when Hydrogen ion combines with a hydroxide ion.
What is water (H+ and OH-)
200
This is the Arrhenius definition of a base
What is OH- producer
300
acid + base =>? + ?
What is water and a salt
300
we know that catalysts speed up a reaction. True or false catalysts are used up in a reaction like a reactant.
What is false: catalysts are not considered reactants because they are not used up in the reaction
300
CO(g) + H2O (g) <-> CO2(g) + H2(g) + 120kJ this is a method of shifting the equilibrium towards the reverse reaction.
What is different options
300
when an acid is added to a base this is what will happen to the hydroxide ion concentration
What is it will decrease
300
The Bronsted Lowry definition distinguishes an acid from a base in this way
What is an acid is an H+ donor while a base is an H+ acceptor
400
a small amount of a weak dilute base is added to a large amount of a strong concentrated acid. the solution will now be a) acidic b) basic c) neutral
What is a) acidic but slightly less acidic
400
this is what happens to the concentration of reactants during the course of reaction. and this is what happens to the concentration of products in the course of the reaction.
What is decrease for reactants (they get used up) and increase for products (more are formed)
400
GREEN CuCl4 <-> Cu + 4Cl + heat BLUE the solution is cooled down. the resulting color will be:
What is blue
400
this is why acids and bases are considered electrolytes
What is the they ionize
400
100 HCL molecules, when dissolved in water, this is how many H+ ions will be in solution.
What is 100 (100% ionization)
500
If a base is added to an acid the H+ concentration will:
What is decrease
500
reaction 2A + 4B -> 8C. if A is used up at a rate of 6 moles/ sec, what is the rate that C will be produced
What is 24 moles/ sec. C is produced 4x the amount that A is used up. so if A is used up at 6mol/sec. multiply 6 x 4=24
500
In a sealed bottle that is half full of water, equilibrium is attained when water molecules:
What is evaporate and condense at the same rate
500
based on the collision theory, this would be a way that a catalyst could help speed up the reaction
What is reposition the reactants to collide in a more effective method
500
this is the difference between strong (acids and bases) vs. weak (acids and bases)
What is the amount of dissociation (ionization). strong ionize 100%
