Question 3
In a creative experiment, grade five students examined effects of different kinds of packed fruit juice on chicken bone. They provide equal amount of different kinds of fruit juice and measure their pH with pH indicator. They collected the chicken bones, and put equal mass of chicken bone in each fruit juice for a month. To prevent juices evaporation they used suitable tight flasks. At the end of the time they measured the mass of each flask bone with a digital scale.
pH for each fruit juice is measured using pH indicator:
| Fruit juice 1 | Fruit juice 2 | Fruit juice 3 | Fruit juice 4 |
| --- | --- | --- | --- |
| 2 | 6 | 4 | 7.5 |
Due to the experiment, which diagram shows the chicken bones mass correctly?
