Crazy Chris: Oh! Hi! I ‘m Crazy Chris and welcome to so cool science, science you can do right in your own home. I’m just enjoying some pink and going over today’s science file, today’s science file says,
What are acids and bases? How do we tell which is which?
That’s a very good question. Well, try this.
You will need 2 clear plastic pop bottles, house hold chemicals like lemon juice and bleach, and some cabbage, start by boiling some water, place two cabbage leaves inside a cup, have an adult pour the boiling water on top of the leaves let that set for about 10 minutes. Then blend the entire mixture. Strain it you got you self some cabbage juice, all right, all that you have made your special cabbage juice inside that have a little fun. Did you get juice or some of that cabbage juice in that you want it empty pop bottle containers, its time to have a little fun, before we go any further, one more thing we need, wear a safety glass, and Ii make me look smart don’t think. Take it on the container, and pour in some lemon juice, and pour some of your cabbage juice inside here.
Or some of your cabbage juice inside here take the empty container, pour in little bit of bleach, and pour some of your cabbage juice inside here. Wow that’s so cool, now what’s going on here well let’s take look,
Scientist could tell if a substance is an acid or base, by means of an indicator, an indicator is typically a chemical that changes color if it comes in contact with an acid or a base, cabbage juice is just on the many indicators that are available in scientist. As you can see the purple cabbage juice turns red when it mixed with the lemon juice, an acid or yellow when it mixed with the bleach, pace, usually pace is turn blue but because of bleach has such a high ph level, in turned yellow. If there is milk color change it all the substance usually is neutral.
Wow, you are going to do this experiment at home, make sure you have an adult person present but that -- straight to work, well I make sure and then you can walk away from the experiment and leave another day, a highest at home with having the house hold chemicals find out what chemicals are acids and which one is bases. You know changing cabbage juice different colors is why science, so cool.
