Lesson 5: acids and bases Contain Hydrogen

Lesson 5: acids and bases Big Idea #3 – Properties of Bases taste bitter feel slippery when dissolved in water

Lesson 5: acids and bases Taste Bitter

Lesson 5: acids and bases Slippery when Dissolved in Water

Lesson 6: Identification of Compounds precipitate - A solid that forms as a result of a chemical reaction. A white solid precipitate may form when aluminum chloride is added to a substance that contains aluminum. residue- A substance left over as a result of a chemical reaction. The black residue left over from burning fossil fuels or wood is carbon. This Photo by Unknown Author is licensed under CC BY-SA This Photo by Unknown Author is licensed under CC BY-SA

Lesson 6: Identification of Compounds Changes in Temperature * NOT ALWAYS an indicator of a chemical reaction

Lesson 6: Identification of Compounds Changes in Color * NOT ALWAYS an indicator of a chemical reaction

Lesson 6: Identification of Compounds Release of a Gas * NOT ALWAYS an indicator of a chemical reaction

Lesson 6: Identification of Compounds Formation of a Precipitate * NOT ALWAYS an indicator of a chemical reaction

Type your answer in the chat box! REVIEW TIME! Type your answer in the chat box! Name 2 indicators that a chemical reaction has occurred.

Raise your hand to be given the microphone! Is a change in temperature ALWAYS an indicator of a chemical reaction? Defend your answer: WHY? or WHY NOT?

pH test for acids and bases flame test for metals and carbon Exit Ticket: Use the polling tool to answer the question before you exit the room. Which of the following methods can tell you whether there is a particular compound or element in a product or reaction? pH test for acids and bases flame test for metals and carbon iodine test for starch all of the above
