Why methyl orange in basic medium is yellow and why it is red in acidic medium?

Sholpan [36]

Methyl orange shows red color in acidic medium and yellow color in basic medium. Because it changes color at the pKa of a mid strength acid, it is usually used in titration for acids. Unlike a universal indicator, methyl orange does not have a full spectrum of color change, but it has a sharp end point.

If hydrochloric acid has a [H+] of 1.2 x 10-2 M, what is the pH?<br> 1.9<br> 0 1<br> 1.2<br> O<br> 8

Vanyuwa [196]

Answer:

<h2>1.9</h2>

Explanation:

The pH of a solution can be found by using the formula

$pH = - log [ {H}^{+} ]$

From the question we have

$pH = - log(1.2 \times {10}^{ - 2} ) \\ = 1.920818...$

We have the final answer as

<h3>1.9</h3>

Hope this helps you
