Molecular & Ionic Substances Flashcards
Properties of ionic compounds (5)
Crystalline solids at room temp High melting and boiling points Will stay crystalline even when broken Most are usually soluble When dissolved in water, the solutions will conduct electricity
A solution that conducts electricity is called an ______
Electrolyte
If ionic substances are molten or melted it will still conduct electricity, true or false?
True
______is a measure of how well a substance dissolves in a solvent
Solubility
If an ionic compound dissolves in water it will form an ______solution
Aqueous (aq)
If an ionic compound is not soluble in water a solid ______ is formed
Precipitate
Properties of molecular compounds (5)
S, L, or G at room temp Low melting and boiling points Will crumble easily when broken Only some are soluble in water Molecular compounds never conduct electricity in any form cause they don't have charges
Water molecules have a strong ______for one another
Attraction
This attraction force between water molecules is called a ______
Hydrogen bond
Properties of water molecules (2)
High melting and boiling points
Large capacity to absorb heat energy without large changes in temperature
An acid is a compound that contains ______ and dissolves in water to form a solution that has a ph ______than 7
Hydrogen
Less
Properties of acid (5)
Sour taste Does not have a slippery feel React with metals to form hydrogen gas Red litmus paper Conduct electricity
A base is a compound that contains ______ and dissolves in water to form a solution that has a ph ______than 7
Hydroxide ion (OH-) More
Properties of bases (5)
Bitter taste Slippery feel Do not react with metals Blue litmus paper Conduct electricity
Acids ionize
Form ions
