There are different types of indicators for different neutralization reactions. The best indicator for giving a colour change at the equivalence point of a neutralization reaction depending on the pH range of a particular indicator and the equivalence point of the reaction. For instance, the best indicator for a neutralization reaction that involve the titration of NaOH with an acid which result in 9.00 equivalence point is phenolphtalein. This is because the equivalence point which is 9.00 is within the pH range of the indicator, which is between 8.0 to 10.1.

Answer:
58.61mL
Explanation:
V1 (initial volume) =?
T1 (initial temperature) = 320 K
V2 (final volume) = 50mL
T2 (final temperature) = 273 K
Using the Charles' law equation V1/T1 = V2/T2
The initial volume of the gas can obtained as follow:
V1/320 = 50/273
Cross multiply to express in linear form
V1 x 273 = 320 x 50
Divide both side by 273
V1 = (320 x 50)/273
V1 = 58.61mL
Therefore, the initial volume of the gas is 58.61mL
Answer:
Carbon atom is a chemical element with the symbol C and atomic number 6 ( electrons). While Hydrogen atom is an atom of the chemical element hydrogen that have only 1 electron.
Explanation:
Answer:
at the oxygen end electron density lies
Explanation:
Carbonyl group is a functional group which is formed when oxygen combined with carbon through a double bond
So the carbonyl group is 
in this the oxygen has more electronegativity than carbon so oxygen attracts the electron density towards itself
So the electron density lies on the oxygen in a carbonyl group
