Question Video: Detecting the Type of Solution of Ocean Water from Its pH Value Chemistry • First Year of Secondary School

Video Transcript

Ocean water has a pH of eight. Is it acidic, basic, or neutral?

pH is a measure of acidity. Typically, the range of pH values for solutions is zero to 14. Seven sits in the middle. The pH of water at 25 degrees Celsius, pH seven, is considered neutral. A solution with a pH less than seven is acidic. And a solution with a pH greater than seven is basic. The question tells us that the pH of ocean water is eight, which is greater than seven. Therefore, ocean water is basic.
