10.1 and 10.2 Quiz
Question | Answer |
---|---|
Ionic Compounds | an attraction between oppositely charged ions |
Covalent Compounds | a chemical compund that is formed by the sharing of electrons |
Difference between Ionic and Covalent Compounds | Ionic: transfer of electrons Covalent: sharing of electrons |
Acid | any covalent compound that increases the number of hydronium ions when dissolved in water |
Acid Properties | change the colors of indicators, such as blue litmus paper to red,sour,corrosive, react with some metals to make hydrogen gas, conduct an electric current when in solution. |
Uses of Acids | paper,paint,detergents,fertilizers,rubber,plastics,sharp taste to drinks |
How do you identify acids using indicators? | when an acid is added to blue litmus paper, the color of the litmus changes to red |
Base | any compound that increases the numbeer of hydroxide ions when dissolved in water |
Base Properties | increases the concentration of hydroxide ions, OH-, when dissolved in water ,bitter, slippery, corrosive,Red litmus paper turns blue when a base is added,do not react with metals,conduct an electric current when in solution |
Uses of Bases | soap,paper,cement,plaster,fertilizers,treat heartburn,unclog drains |
How do you identify bases using indicators? | Bases change the color or red litmus paper to blue. Bromthymol blue, turns a darker blue when a base is added to it |
What happens when a metal reacts with an acid? | Hydrogen gas is produced |
