Is methyl orange the indicator used in the titration of na2co3 against hcl solution?
No, methyl orange is not commonly used as the indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is the indicator of choice for this titration, as the endpoint is at a pH of around 8.2, which is the color change range of phenolphthalein.
Which indicator is suitable for the titration of washing soda against HCL and why?
Phenolphthalein is a suitable indicator for titration of washing soda (sodium carbonate) against hydrochloric acid. This indicator changes color in the pH range of 8.2 to 10, making it ideal for this titration since the end point occurs when all the sodium carbonate has reacted to form sodium chloride and carbonic acid, resulting in a pH above 8.2.
Is phenolphthalein the indicator used in the titration of Na2CO3 against HCl solution?
Type your answer here... Phenolphthaelin indicator changes its colour at 8.3 pH. But the end point of this reaction is at pH 7. In weak base Strong acid case the curve gives sharp change from 3.2 to 6.0 pH. Hence phenolphthalein indicator will not be advicable.
Why is a white tile used in an acid - base titration?
A white tile is used in an acid-base titration to provide a clear background against which to observe the color change of the indicator in the solution being titrated. The white surface helps enhance the visibility of the color change, allowing the endpoint of the titration to be detected more accurately.
What is the product of titration?
The product of a titration is a titration curve, which is a graph showing the pH or volume of titrant added against the concentration of the analyte in a solution. The shape of the curve can reveal information about the equivalence point, endpoint, and buffering capacity of the solution.

What indicator in titration of sodium carbonate solution against hydrochloric acid would give a complete neutralization?
The indicator methyl orange can be used in the titration of sodium carbonate solution against hydrochloric acid to give a complete neutralization. At the endpoint, when all the carbonate ions have reacted to form bicarbonate ions, the solution will turn from yellow to pink.

What are the best indicator use in titration of weak base against strong acid?
The best indicator to use in the titration of a weak base against a strong acid is phenolphthalein. Phenolphthalein changes color from colorless to pink at a pH range of about 8.2 to 10.0, which is suitable for detecting the endpoint of the titration when the weak base is completely neutralized by the strong acid.
Why phenolphthalein cannot be used as an indicator for titrating a weak base against a strong acid?
Phenolphthalein is not suitable for this titration because its color change occurs over a pH range that is beyond the equivalence point of the weak base and strong acid titration. At the equivalence point of this titration, the solution is acidic, which is below phenolphthalein's color change pH range. This can lead to inaccurate results and difficulty in determining the endpoint of the titration.
What type of titration is involved in the assay of milk of magnesia?
The assay of milk of magnesia typically involves an acid-base titration. In this process, a known concentration of hydrochloric acid (HCl) is titrated against the magnesium hydroxide present in milk of magnesia. The endpoint of the titration is indicated by a pH indicator, which changes color when the solution reaches neutrality, allowing for the calculation of the magnesium hydroxide content in the sample.
Why is phenolphthalein indicator used in the titration of oxalic acid against sodium hydroxide?
Phenolphthalein is used as an indicator in the titration of oxalic acid against sodium hydroxide because it undergoes a color change at the pH region where the reaction between oxalic acid and sodium hydroxide is neutralized. Oxalic acid is a diprotic acid, meaning it requires two equivalents of sodium hydroxide to be fully neutralized. Phenolphthalein changes color at a pH of around 8.2-10, which is ideal for indicating the endpoint of the titration.
Best indicator for lactic acid when titrated against standard NaOH?
The best indicator for titrating lactic acid against standard NaOH is phenolphthalein. It changes color in the pH range of about 8.2 to 10, which is suitable for the endpoint of the titration of lactic acid (pKa ≈ 3.9). This indicator appears pink at high pH and colorless at acidic pH, allowing for a clear visual indication of the endpoint of the titration.
Detect equivalence point in titration without an indicator?
Titration without indicator is only possible with another measurement:Examples / possibilities:pH-electrode measurement (acid-base titration)Conductivity measurement (acid-base titration or ion-reaction)Change of color by excess or depletion of the reactant/titrant (redox titration)Precipitation by excess or depletion of the reactant/titrantAdded:(The following was more or less written for 'indicator' titrations, but same principles count for other 'sharply' changing properties):The equivalence point is the point where the number of moles of titrant equal the number of moles of the reactant. The end point is the point where the indicator being used changes color (also 'indication point)'.If the indicator is chosen correctly, the end point will essentially be as near as possible at the equivalence point.The point of the titration is to find the equivalence point -- the end point is just a very close approximation to it. This is because the pH of the solution changes very rapidly close to the equivalence point.Therefore, the indicator will change color very close to the equivalence point because of the steepness of the pH change
