Question

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.

Answer 1

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?

if wrong i sry :(

Answer 2

Answer:

Sample response: How is pH used to determine if a solution is acidic or basic?

Explanation:

What did you include in your question? Check all that apply.

focuses on the pH scale

suggests a way to measure how acidic or basic a solution can be

allows for observations and an opportunity to look at pH quantitatively and qualitatively
