Question

a student wanted to understand the difference between sea water and fresh water. they did this by comparing the ph and the alkalinity or saltiness of the water. what is a conclusion that the students can make based on the graph? a. sea water has a higher alkalinity (saltiness) than freshwater. b. the amount of alkalinity shows an exponential decrease over time. c. as ph increases alkalinity decreases. d. alkalinity shows a constant acceleration over time.

Explanation:

By observing the graph, we can see that sea - water has a higher value on the alkalinity axis compared to freshwater at the same pH levels. So we can conclude that sea water has a higher alkalinity (salinity) than freshwater.

Answer:

A. Sea water has a higher Alkalinity (saltiness) than freshwater.
