ph2 balance lab
we did a couple of experiments with this lab. We used tum's and crushed them into pieces. Then we had a few liquids that we used. We had vinegar, water baking soda, and sugar. We had to check the pH balance on all of those liquids. As you can see from the chart how much the balance was on each one.
After we checked the pH balance we mixed the substances together and it bubbled and made a purple substance. After it fizzled down it left a thin layer of skin on the top of the beaker and the rest of the substance had drained to the bottom.
This is when the substance was bubbling and changing colors
This was the top thin layer of skin that the substance left in the beaker
The top layer of skin looked like gum. This substance was made with crushed up tums and added vinegar. We tried to have the same result when we used a different substance with vinegar and it did not work. It just fizzled and turned into white liquid.

Nice job at explaining what you used but, you should explain why you used them. You should also explain what your hypothesis was and, if you were right. But, all in all you did an amazing job.
ReplyDeleteI think you did a good job but you should have explained why you were using what you were using. I didn't see what your hypothesis was, You should have included that in there. Other than that you did a pretty nice job on this.
ReplyDeleteThis post made me realize that this post is just your procedure, try adding in other data to show what was occuring. Why it made me realize this is after each picture you just have what you did during the experiment.
