Question
Rank the following solutions from most acidic to least acidic. (4 points)
soapy water, black cofee, orange juice, and seawater

Answer 1

To rank the solutions from most acidic to least acidic, we can consider their typical pH levels:

1. **Orange juice** - Typically has a pH range of about 3 to 4, making it quite acidic.
2. **Black coffee** - Usually has a pH around 4.5 to 6, which is less acidic than orange juice but still mildly acidic.
3. **Seawater** - Generally has a pH around 7.5 to 8.5, which is slightly alkaline.
4. **Soapy water** - Generally has a pH greater than 9, making it basic (alkaline).

Based on this information, the ranking from most acidic to least acidic is:

1. Orange juice
2. Black coffee
3. Seawater
4. Soapy water
