What happens when sodium hydroxide reacts with sulphuric acid?
A reaction between sulfuric acid and sodium hydroxide is of an acid-base type, or is also known as a neutralization reaction. In this process, both compounds undergo a reaction to neutralize the acid and base properties. The products of this process are salt and water.
When we do a titration reaction NaOH and H2SO4 for this reaction What is the pH at the equivalence point?
At the equivalence point, equal amounts of H+ and OH- ions will combine to form H2O, resulting in a pH of 7.0 (neutral).
What is a suitable indicator for titrating sodium hydroxide and sulphuric acid?
In this experiment involving a reaction between sodium hydroxide (titrant) and sulfuric acid (titer), an indicator called phenolphthalein is used. It is colorless in acids, and its endpoint is marked by a color change to pink, when the entire volume of the analyte has reacted with a small amount of the titrant.
What is the Colour of the solution at the end point during the titration of sodium hydroxide and sulphuric acid phenolphthalein is used as indicator?
pink
The indicator phenolphthalein is pink in basic solutions and colorless in acid solutions. The solution for the titration of sulfuric acid with NaOH changes from acidic (indicator colorless) to basic (indicator pink) at the endpoint.
What will happen if NaOH is used in place of dilute sulphuric acid and the test tube is heated?
(d) If sodium hydroxide is taken in place of dilute sulphuric acid and the tube is heated then the metal will react with the base to form the corresponding salt and will evolve hydrogen gas as per the following reaction: Zn+2NaOH→Na2ZnO2+H2.
What is the equivalence point of NaOH and H2SO4?
But it is not so simple, so we can just treat it as a standard stoichiometry problem. At the equivalence point, we have: [NaOH]=moles of NaOH/L NaOH = moles H2SO4 (2 mol NaOH/mol H2SO4) / L NaOH Page 2 but moles H2SO4 = [H2SO4] x (L H2SO4) = (0.25mol/L)(0.0150L).
What will be the end point of this titration?
indicator colour change is the end point of the titration. The end point is used as an approximation of the equivalence point and is employed, with the known concentration of the titrant, to calculate the amount or concentration of the analyte.
What is the colour of the solution at the end point during the titration of sodium hydroxide and sulphuric acid methyl orange is used as indicator?
In this case, hydrochloric acid is taken in the burette and sodium carbonate solution in the conical flask. Methyl orange is used as an indicator. The colour change at the end point will be from yellow to pinkish-red.
What is the colour of the solution at the end point during the titration of sodium hydroxide and sulphuric acid methyl orange is used as indicator *?
2 Answers. End point shows pale pink colouration.
Why does phenolphthalein turn pink in sodium hydroxide?
Normally, all colours of the light pass through the Phenolphthalein solution and it appears colourless. But, when it exposed to alkaline then it starts to block the blue colour of the light spectrum, which turns the light pink.
What occurs at the endpoint of a titration?
The endpoint in titration refers to the point at which the indicator changes colour in the colourimetric titration. For example, in complexometric titration, if Eriochrome Black T is used as an indicator, then at the endpoint, colour changes from wine red to blue.
