1. If you were to mix a weak acid with water, what would you expect to observe
regarding the concentration of ions in solution compared to a strong acid
mixed with water?
The concentration of ions would be higher in the weak acid solution
compared to the strong acid solution.
The concentration of ions would be lower in the weak acid solution
compared to the strong acid solution.
The weak acid would not produce any ions in solution.
The concentration of ions would be the same in both solutions.
2. Describe the behavior of a strong electrolyte when it is mixed with water.
A strong electrolyte dissociates completely into its constituent ions,
allowing for high conductivity.
A strong electrolyte only partially dissociates, resulting in low
conductivity.
A strong electrolyte remains intact and does not change in solution.
A strong electrolyte forms a gel-like substance in water.
3. Describe the difference between a weak electrolyte and a strong electrolyte
in terms of ion dissociation in water.
Weak electrolytes only dissolve in water, while strong electrolytes do
not.
A weak electrolyte does not dissociate, while a strong electrolyte
partially dissociates.
Both weak and strong electrolytes completely dissociate into ions.
, A weak electrolyte partially dissociates into ions, while a strong
electrolyte completely dissociates into ions.
4. Which is an Arrhenius base?
HBr
NH3
LiOH
5. A chemical equation is based when:
The total number of molecules is the same in reactants and products
The total number of ions is the same in reactants and products
The number of atoms of each element is the same in reactants and
products
The charge on each atom is the same in reactants and products
6. What is the formula for calculating dilution in chemistry?
PV = nRT
C1V1 = C2V2
C = m/V
V = n/C
7. If a solution containing sodium chloride is mixed with silver nitrate, which
type of chemical reaction occurs, and what is the expected product?
Precipitation reaction, forming silver chloride
Decomposition reaction, forming sodium and chlorine
