What is an Acid? What is a base?
In today's experiment, we will be testing solutions and seeing if they are an acid or a base.
Here are the supplies you will need.
Testing products
Directions:
Wear your Goggles!
Gather your supplies and work with an adult. We have ammonia today and you must have a big kid or grown up helping.
The blue litmus paper will turn red if it is an acid. The red litmus paper will turn blue if it is a base. In your science notebook, write each product we are testing. After you test a product, write if it is an acid or base: and how you know.
3. Start an entry is your notebook for today. We are going to find the elements is Salt and Baking Soda. Salt is a compound of Sodium and Chlorine so
Your entry starts like this,
SALT = Sodium and Chlorine
Sodium is at the ______ of the video. Element symbol = Atomic Number =
Chlorine is at the ______ of the video. Element symbol = Atomic Number =
4. Now view our video of the periodic table (color) write down where you find the elements in salt. Remember, salt is a compound of two elements, Sodium and Chlorine. You will look for both elements and record where you find them in the video. Then you will go to our Periodic Table (STAR) CLICK HERE and write down the elements symbols and Atomic numbers.
5. Baking Soda has four elements, Sodium, Hydrogen, Carbon, and Oxygen. You will need to write all four elements in your notebook, but you found Sodium already when you found salt. You also found Oxygen in another Lesson. A savvy student will find the answers they already recorded and use them again. I believe you have already found Carbon and Hydrogen too. You can look for them in the video and on our STAR periodic table or be savvy and find them in your notebook. Either way, you must record them in your notebook just like you did for salt.
