1. the ph of lemon juice is about 2.0, whereas tomato juices ph is about 4.0. approximately how much of an increase in hydrogen ion concentration is there between tomato juice and lemon juice?

a. 2 times
b. 10 times
c. 100 times
d. 1000 times

1. why can insects walk on water?
2. explain why water is an excellent solvent?

Explanation:

Step1: Calculate pH difference

pH difference = 4.0 - 2.0 = 2

Step2: Relate pH to H+ concentration

[H+] ratio = 10^(pH difference) = 10^2 = 100

Due to surface tension from water's cohesive forces.

Water's polarity enables dissolving polar/ionic substances via hydrogen bonding.

Answer:

c. 100 times
