Chem 1 Flashcards
What is the process of separating a solid from a liquid by passing the mixture through a filter?
Filtration
True or False: Crystallization is a method used to separate dissolved solids from a solution.
True
What is the purpose of distillation in chemistry?
To separate components of a mixture based on different boiling points.
Fill in the blank: A ________ is a homogeneous mixture of two or more substances.
solution
What is the main difference between filtration and crystallization?
Filtration separates solids from liquids, while crystallization separates dissolved solids from solutions.
Which method would be best suited to separate a mixture of salt and water?
Distillation
True or False: In crystallization, the solute is cooled to form crystals.
True
What is the term for the liquid that remains after crystallization?
Mother liquor
What is the role of a filter paper in filtration?
To allow liquids to pass through while retaining solids.
Multiple Choice: Which of the following is NOT a method of separation in chemistry? A) Filtration B) Crystallization C) Mixing D) Distillation
C) Mixing
What is the primary factor that affects the efficiency of distillation?
Boiling point of the components in the mixture.
Fill in the blank: The solid formed during crystallization is referred to as a ________.
crystal
What type of mixture can be separated by filtration?
Heterogeneous mixtures
True or False: Distillation can be used to purify liquids.
True
What is the technique called when a solution is heated to evaporate the solvent and leave behind the solute?
Evaporation
Fill in the blank: The process of heating a liquid to form vapor and then cooling the vapor to form a liquid is called ________.
distillation
What is the outcome of the crystallization process?
Formation of solid crystals from a solution.
Multiple Choice: Which of the following is a characteristic of a solution? A) Uniform composition B) Variable composition C) Visible particles D) All of the above
A) Uniform composition
What is the term for the substance that is dissolved in a solution?
Solute
True or False: In a solution, the solute is present in a greater amount than the solvent.
False
What is the main purpose of using a separating funnel?
To separate immiscible liquids.
Fill in the blank: The liquid used to dissolve a solute is called the ________.
solvent
What is the result of incomplete crystallization?
Impure crystals
