Comic Strip - Acids and Bases Neutralization
Storyboard Text
- Hey Mia, school was so tough today. I didn't understand what the teacher was saying in science. He just kept talking on and on about acids and bases.
- Don't worry, Olivia,  I'm here to help. I love science, but it can be tricky sometimes. Let me explain how the acids and bases work.
- Acid(1-6)
- You're teacher might've mentioned a pH scale. A pH scale shows if a substance is an acid, neutral, or a base. Lemon juice isan acid, with a pH of 2. Water is neutral, with a pH of 7. A really important fact to remember is that water AND salt are neutral. An egg is a base. with a pH of 8. These are just some examples of each section. 
- Neutral(7)
- Base(8-14)
- Oh, wow! That's really cool. That's why a lemon tastes really sour.
- Exactly! But there are a couple more facts to know about acids, bases, and how they're neutralized.
- strong acid + strong base = neutral solution
- Like you mentioned, acids are sour. They form hydrogen ions, or more commonly known as H+. They're corrosive, meaning they destroy substances who come in contact with them. They react with metal, and neutralize bases. In both cases, when you add a strong acid and a strong base, it equals a neutral substance. Just like we saw on the pH scale, all acids have a pH of less than 7.
- Bases are a bit different. They form hydroxide ions, or referred to as OH-. They're slippery and taste bitter. However, it's also corrosive and reacts with metal. They're pH is always greater than 7. Just like an acid neutralizes a base, a base neutralizes an acid. It can help to remember that acids are blue and bases are red. When an acid and base mix, they make water or salt because they're both neutral substances.
- I know it's a lot of information. But, was it helpful?
- Yea, it was really helpful. I could picture all of the information in my head. Thank you so much! You're a lifesaver, Mia!
- No problem, anytime. If you need help for anything else let me know. Especially for tests and quizzes. I think we should get going now or we'll miss the show. Come on!
