How do pH indicator dyes show a change in pH from acidic to basic or vice versa?

Certain indicators only change colour when placed in a particular pH level or range (e.g. litmus) and others are colourless in certain conditions (e.g. phenolphthalein, leuchomalachite green's second transition).

Why is an indicator a valuable tool for measuring pH?
Most acidic solutions and basic solutions are colourless and transparent. Therefore, you cannot tell the difference between an acid and a base by appearance alone. One safe way to determine wether something is an acid or a base is to use an indicator.
How does a pH reading of 5 differ from 6?
It is 1 less. Stupid. Just kidding, remember what does the p stand for in pH? POWER of hydronium. PH is -log[H3O+], so a decrease would mean a higher concentration of Hydronium. Remember it's a logarithmic scale, so a change of 1 means a change of 10 times.
Is it possible to have surgery to change your voice?
Yes you can change your voice by having pressure put on or removed from the voice box and vocal cords, but no you can not have a 100% voice change example: male to female. you can get it from a male voice to female voice or vise versa but never can you completely change your voice.

How write a short note on the effect of temperature on the change of state of matter?

Why indicator change color?
Indicators are mostly organic aromatic compounds in acidic to basic medium or vice versa the resonating structures of indicators become change which are responsible to change the colour.
How do you classify the aqueous solution acidic or basic?
By observing the [H+] ion concentration and [OH-] concentration in the aqueous solution. If the [H+] ion concentration is higher that the [OH-] ion concentration, it is acidic. Vice Versa for basic.
Why might a scientist prefer to use Universal Indicator rather than a different indicator like litmus?
Litmus only differentiates between acidic and alkaline solutions. It does not give an accurate value of the degree of acidity of alkalinity. Universal Indicator can help measure the pH of the given solution as it does not just change from red to blue and vice versa, but in solution has a range of colours.
