Acids have a ______ taste.
1 / 10
Yo, what's good everybody? It's Ike on the mic.
And Sumeet.
Flocabulary in the building!
Acids and bases are compounds that are found all around,
And I don't mean bass like that 808 sound.
These compounds have very different properties,
Let me specify, so you understand properly.
Acids can be dangerous to touch
And have a sour taste, don't taste, just trust.
They react strongly with metals and conduct
Electricity that could light the room up.
Examples include oranges, vinegar, and lemons,
If there's hydrofluoric acid better run like Reverend Simmons.
Other acids include hydrogen sulfide,
Hydrochloric acid and sulfuric acid, let's slide into
Bases, hold up, they could also be dangerous,
And have a bitter taste, don't try to found out what the taste is.
Again, just trust, they could also conduct
Electricity that could light the room up.
They feel slippery, picture this imagery:
Squeeze a bar of soap, and see it shoot out like a missile, see?
Aye, soap is a base and baking soda, too,
Sodium hydroxide and your shampoo.
Have you ever heard about the pH scale?
Goes from 0 to 14, if you couldn't tell,
Measures the acidity and alkalinity of a solution,
Know seven equals neutral, there's no confusion.
I'll tell you about the pH scale,
Goes from 0 to 14, if you couldn't tell.
The lower the pH, the more acidic,
The higher the pH, the more alkaline, if you get it then you get it, hey.
You know my flow is hot as an incinerator,
Now let me give you more info about an indicator.
It's a special compound that changes color
In the presence of an acid or base, so we discover
What the pH of the substance is.
Want a good example? Red cabbage juice is
A common indicator and litmus paper, too.
In an acid it's red, and in a base it's blue.
Do you know what happens when an acid and a base combine?
It's predictable, happens every single time.
New substances are formed, with new properties,
You can know that ahead of time like prophecies.
The reaction will produce water and a salt,
Lock this last piece of info in your brain vault.
The new pH will be closer to seven,
That means closer to neutral, I hope you find it useful.

Acids and bases are found all around us. In this lesson, students will learn about their properties, the pH scale and what happens when acids and bases react.
