Question

If an orange colour in produce then the ph wil be around 4

Answer 1

Answer:

yes

Explanation:

the solution is acidic so the Ph is 4.

Answer 2

Answer:

You see a demonstration of a color change using universal pH indicator. Students will change the concentrations of an acid and a base and use universal indicator to test the pH of the resulting solutions. Students will see an animation showing that water molecules interact and separate into the H3O+ion and the OH− ion. Students will see that the pH of a solution is related to the concentration of these ions in water. The molecular level, that pH is a measure of the concentration of the H3O+ions in water and that adding an acid or a base to water affects the concentration of these ions.
