A compound whose water solution conducts electricity and turns phenolphthalein pink is

Chemistry
1 answer:
Ede4ka [16]3 years ago
4 0

Answer:

The compound is an <em>alkali</em>

Explanation:

Although acids and bases in solution can conduct electricity due to the presence of free ions available to carry charges, bases or alkalis turn phenolphthalein indicator pink; as opposed to acids which give colourless test on the indicator.

The anayte compound is therefore a concentrated alakli solution.

From Young's experiment, how does the frequency of light affect the number of lines observed?
Marina CMI [18]

Answer : (C) "Higher frequencies have larger spaces between lines".

Explanation:

In Young's experiment, the condition for constructive interference is given by :

dsin\theta=n\lambda.........(1)

n is order or number of lines observed

d is distance between slits

\theta is the angle between the path and the line from screen to the slits.

We also know that, c=\nu \lambda

or

\lambda=\dfrac{c}{\nu}

where,

c is the speed of light

\nu is frequency

\lambda is wavelength

So, equation (1) turns into

dsin\theta=n\dfrac{c}{\nu}

\nu=\dfrac{n\ c}{d\ sin\theta}

So,

\nu\propto n

or

Higher frequencies have larger spaces between line.

So, correct option is (C).
