1 answer

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
