Methyl orange is also known as H + In -. Its dissociation constant for its ionic strength is 0.1 mol I-1 in water, at 25 degrees Celsius.
the color of methyl orange in an acidic medium is orange
IN ACID: it turns methyl orange pink In base: it turns methyl orange yellow
Methyl orange is yellow in alkaline conditions.
Methyl orange is red under a pH=3,1 and yellow over a pH=4,4; methyl orange is useful for the titrimetric determination of acids concentration.
The equilibrium constant for the dissociation of acetic acid in water is known as the acid dissociation constant (Ka) and is approximately 1.8 x 10-5.

Methyl orange and screened methyl orange are both synthetic dyes commonly used as indicators in titrations. They both change color at specific pH ranges: methyl orange transitions from red to yellow in acidic solutions, while screened methyl orange transitions from yellow to red in basic solutions. Both dyes are water-soluble and widely available for laboratory use.
To prepare methyl orange indicator for titration, dissolve 0.1g of methyl orange powder in 100mL of distilled water. This will give you a 0.1% solution of methyl orange which is suitable for use as an indicator in acid-base titrations.
Methyl orange is a pH indicator having the chemical formula C14H14N3NaO3S.
Methyl orange appears yellow in alkaline solutions.
The dissociation constant of an acid is affected by factors such as temperature, solvent, and ionic strength of the solution. Increasing temperature generally leads to higher dissociation constants, while changes in solvent polarity can also impact the dissociation constant. Additionally, the presence of other ions in the solution can affect the dissociation constant by influencing the equilibrium position of the acid dissociation reaction.
The acid dissociation constant (Ka) for an acid dissolved in water is equal to the ratio of the concentration of the products (H+ and the conjugate base) over the concentration of the reactant (the acid). It represents the extent of dissociation of the acid in water.
