Concentration & Solutions
This is the term for the amount of solute dissolved in a certain amount of solution.
What is concentration?
According to Arrhenius, this produces H⁺ ions in water.
What is an acid?
These compounds dissociate into ions and conduct electricity in water.
What are electrolytes?
This law states that P1V1=P2V2 at constant temperature.
What is Boyle’s Law?
Adding more reactant to a system at equilibrium shifts the reaction in this direction.
What is the forward (toward products) direction?
To find this percent, divide grams of solute by grams of solution and multiply by 100.
What is mass percent (% m/m)?
This base property makes your skin feel slippery.
What is slippery/soapy?
NaBr dissolved in water is an example of this type of electrolyte
What is a strong electrolyte?
At STP, one mole of any gas occupies this many liters.
What is 22.4 L?
This type of reaction absorbs heat from the surroundings.
What is endothermic?
This type of percent measures grams of solute per milliliters of solution
What is mass/volume percent (% m/v)?
A weak acid only partially dissociates and reaches this kind of reaction state
What is equilibrium?
CH₃OH does not dissociate in water and is classified as this.
What is a non-electrolyte?
This law relates pressure and temperature of a gas at constant volume: P1/T1=P2/T2
What is Gay-Lussac’s Law?
When acids react with carbonates, this gas is produced
What is CO₂?
A mixture where large undissolved particles settle out and can be filtered is called this.
What is a suspension?
In neutral water, the concentration of H₃O⁺ is equal to this.
What is 1.0 × 10⁻⁷ M?
The formula to calculate equivalents is moles multiplied by this.
What is ion charge?
The law that states V1/n1=V2/n2 is named after this scientist.
Who is Avogadro?
A strong acid like HCl dissociates in this manner.
What is completely?
Molarity is calculated by dividing moles of solute by this.
What is liters of solution?
This type of solution resists drastic pH changes when acids or bases are added.
What is a buffer?
Electrolytes that partially dissociate and conduct electricity poorly are called this.
What are weak electrolytes?
The combined gas law relates pressure, volume, and temperature in this formula.
What is P1V1/T1=P2V2/T2?
The state when forward and reverse reactions occur at the same rate.
What is chemical equilibrium?
