Logarithmic Comic Strip
Текст на Статията
- Hi Shaun! How are we doing today?
- I'm quite confused Claire, you never ask me that question unless you need something.
- We have an assignment in chemistry class, we have to calculate the pH value of water, can you help me?
- Hmm right!
- So? What is it?
- Good thing your bestfriend is good at math! Let's go to my room so I can explain to you better.
- YES!! Thanks Shaun!
- So to start, we can use logarithmic to determine its value, I'm going to show you how it's done you must remember that pure water contains hydrogen ion concentration of 1*10-7 moles.
- Okay okay, I'll keep that in mind.
- So that's how we need to solve it! I never thought that we could apply logarithmic in different situations
- So, to calculate the pH, you must use the formula pH=-log10[H+]. So it's going to look like pH=-log(1*10-7)=-log(1)-log(10-7)=0-(-7)=7
- Thanks Shaun! I never doubted you!
- Yeah, Ithought that too! That's why I practice it most of the time.
