3.3 ASSIGNMENT: Science Blog: Strength of Acids and Bases (Due April 12)
ASSIGNMENT: Science Blog: Strength of Acids and Bases (10 points)
This Week's Science Blog Topic: For this week's blog entry, watch the video below and answer the questions that follow.
- Two important characteristics of acids and bases are: (1) strength and (2) concentration. We talked about strength in the video, but not concentration. What is the difference between a strong acid and a weak acid?
- Vinegar is about 5% acetic acid. Is this a measure of its strength or concentration? Explain.
- If you were given the choice between drinking a solution of 0.1% hydrochloric acid (a strong acid) to 70% acetic acid (a weak acid), which would you choose and why? Is there any additional information you’d need to answer this question? (Note: DON’T DRINK THINGS THAT AREN’T MEANT TO BE DRUNK. THIS IS PURELY A THOUGHT EXPERIMENT.)
Blog Guidelines:
- Each blog post should be at least one paragraph (3-5 sentences minimum).
- Use complete sentences, proper grammar and punctuation.
- All posts/comments must be respectful. Vulgarity or rudeness will result in school disciplinary action.
