Question

Calculate the average (mean) concentration for your juice. 0.053 +0.06 059= 0.173 -0.0571ddob? Other members of your class analysed differentices than you did. From a group that had a different lise fill in the chart below using their average (mean con for their fruit juice. From at least one 70.05811 heir average (mean) concentration Grapefruit Juice Lemon Juice Orange Juice Average citric acid concentration, M 0.0581 0.0224 3 Lime juice contains citric acid and whilst not as sour as lemon juice, it is certainly more sour than both grapefruit and orange juices. Based on this observation, what range of citric acid concentrations will lime juice contain? "Un-ripened fruit juice will give a person an upset stomach where ripened fruit juice will not. What does this statement tell you about the amount of citric acid in un-ripened and ripened fruit juice? Which fruit will taste more sour: un-ripened or ripened? Explain why

please help me answer numbers 3 and 4

Answer 1

3. Acid concentration of lime juice would be more than that of grapefruit juice and orange juice but less than lemon juice.

So the citric acid concentration in lime juice would range from above 0.058 M to less than that of the citric acid concentration in lemon juice.

4. Amount of citric acid would be higher in unripened fruit juice than the ripened fruit juice. Unripened fruit juice will taste more sour. This is due to the presence of higher amount of citric acid which is sour in nature.
