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?
No, phenolphthalein is not the indicator typically used in the titration of Na2CO3 against HCl. In this titration, methyl orange or bromothymol blue are commonly used indicators to detect the endpoint of the reaction between the carbonate ion and the acid.
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.
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?
The equivalence point in a titration can be determined without an indicator by monitoring a physical property of the reaction, such as pH, conductivity, or volume change. By plotting the data collected against the volume of titrant added, a sharp change in the property being monitored will indicate the equivalence point. This method is known as a potentiometric or direct titration.
Why phenolphthalein used as best indicator against NaOH?
Phenolphthalein is a suitable indicator for NaOH because it changes color sharply from colorless to pink at the pH range of 8.2 to 10.0, which corresponds well to the endpoint of the titration of NaOH with an acid. This sharp color change allows for accurate and precise detection of the equivalence point in the titration process.
