The color change of a pH indicator is caused by the dissociation of the H+ ion from the indicator.

<h3 /><h3>What is indicator?</h3>

In science, a marker capability or a trademark capability of a subset An of a set X is a capability characterized from X to the two components set {0, 1}, normally signified as, and it demonstrates whether a component in X has a place with A. Markers are insights used to gauge current circumstances as well as to figure monetary or financial patterns. In the realm of money management, pointers regularly allude to specialized diagram designs getting from the value, volume, or open revenue of a given security.

Metals give up electrons to become cation or anion

galina1969 [7]

Metals usually become cations since electrons are negatively charged and when they are lost there are more protons than electrons making a positive net charge in the atom. (cations are positively charged ions while anions are negatively charged ions)

I hope this helps. Let me know if anything is unclear.

A pool is 59.8 m long and 26.6 m wide. If the average depth of water is 3.70 ft, what is the mass (in kg) of water in the pool?

klio [65]

Given :

Length , l = 59.8 m.

Breadth , b = 26.6 m.

Depth , d = 3.7 ft .

Density of water , $\rho=1\ g/ml=1000\ kg/m^3$ .

To Find :

Mass of water in pool .

Solution :

First we will covert depth into m from ft .

$1\ ft =0.3\ m$

For ,

$3.7\ ft=0.3\times 3.7\ m\\3.7\ ft=1.11\ m$

So , volume of pool is :

$V=59.8\times 26.6\times 1.11\ m^3\\\\V=1765.65\ m^3$

We know , density is given by :

$\rho=\dfrac{m}{V}$

So , $m=\rho V$

Putting given values in above equation :

$m=1000\times 1765.65\ kg\\\\m=1.77\times 10^6\ kg$

Hence , this is the required solution.
