In this experiment, you will use a natural indicator to indirectly determine the H+ concentration of some common household solutions to determine a physical characteristic of the solution. In the space below, write a scientific question that you will answer by doing this experiment.

Some of the scientific questions that may be answered through the experiment are:

(1) What are the physical changes that may occur in the solution or the indicator when added with acidic/basic solution?

(2) How much of the indicator is needed in order to bring about a significant physical change in the solution to identify its H+ concentration?

The scientific questions can be based on the significances and uses of the indicators in various analysis of chemical mixtures or solutions.

Since the content is based on the solutions, where natural indicators play a vital role by determining the hydronium ion concentration [tex](\rm H^{+})[/tex]. Therefore, the possible scientific questions based on this is given as follows:

1. When one solution is added with another solution, is there any physical changes occur? Is yes, then describe those changes.

2. What are the significances of indicators and how it is used to identify the hydronium ion concentration? Also specify the quantity required for the identification.

Thus, we can conclude that scientific questions can be based on the significances and practical analysis of the indicators used in various chemical mixtures or solutions.
