Answer:
Red.
Explanation:
- Methyl orange is an organic dye that used as an indicator in acid-base titrations because its color is changed according to the pH of the medium (acidic, neutral or basic).
- Methyl orange is red in acidic solutions, orange in neutral solutions, and yellow in basic solutions.
<em>Since, pH of the solution is 2, the solution is acidic, the color of the solution will be red.</em>
<h2>Answer : Solid</h2><h3>Explanation :</h3>
When the substance was tested in the lab it was seen that it maintains a unique shape, which is the differentiating property of solids. Also, they are very good conductors of electricity. Solid contains electrons, protons and neutrons this is a common thing which is found in every state of matter. This all details confirms that it will be solid.
Explanation:
The pH of the solution is 9.63 ± 0.03.
we know that
pH= -log[H+]
⇒[H+] =
= =
Now to find absolute error we use the formula
Absolute error/[H+] =ln10(uncertainity)
Absolute error = ln10×[H+] ×0.03
=
