Double indicator titration calculation for mixture of sodium hydroxide and sodium carbonate?
In a double indicator titration for a mixture of sodium hydroxide (NaOH) and sodium carbonate (Na2CO3), phenolphthalein and methyl orange are typically used as indicators. First, phenolphthalein indicates the endpoint for the neutralization of Na2CO3 with a strong acid, showing a color change at a pH of around 8.2 to 10.0. After all Na2CO3 has reacted, methyl orange can be used to determine the remaining NaOH, changing color at a lower pH (3.1 to 4.4). To calculate the concentrations, you need to measure the volume of acid used to reach the endpoints and apply stoichiometry based on the balanced chemical equations for the reactions involved.
What volume of Na-OH is required to flip the indicator from colorless to pink at the endpoint?
The exact volume of NaOH needed to change the indicator to pink will depend on the concentration of the NaOH solution and the amount of acid in the solution being titrated. This can be determined by titrating a known volume of acid with a NaOH solution until the color change occurs.
How many grams of NaOH are in 750 ml 0.600 M NaOH solution?
This solution contain 26,3 g NaOH.
What is the molarity of Na OH solution?
The molarity of a NaOH solution is determined by the concentration of NaOH in moles per liter of solution. It is calculated by dividing the moles of NaOH by the volume of solution in liters. For example, a 0.1 M NaOH solution would contain 0.1 moles of NaOH per liter of solution.
What is the molarity of a solution that contains 10.0g of NaOH in 400.0 ml of NaOH of solution?
The answer is 0,625 moles.
Which indicator is used in titration of naoh and h2so4?
Phenolphthalein is commonly used as an indicator in the titration of NaOH and H2SO4. It changes color from colorless to pink as the solution reaches a specific pH range, signaling the endpoint of the titration.
Can you use indicator other than phenolphthalein in the titration of NaOH?
Yes, you can use indicators such as bromothymol blue or methyl orange in the titration of NaOH. These indicators change color at different pH ranges and can be used based on the specific pH endpoint needed for the titration.
What is the equation of titration with methyl orange?
The equation of the titration using methyl orange as an indicator depends on the specific reaction being titrated. Methyl orange is typically used in acid-base titrations, where the indicator changes color in the presence of a certain pH range. For example, in a titration of a strong acid (e.g., HCl) with a strong base (e.g., NaOH), the equation would involve the stoichiometry of the acid-base reaction, with the color change of methyl orange indicating the endpoint of the titration.
Why methyl orange is used as an indicator in HCL and NaOH titration?
I don't know ... I have the same problem . I found this in a chemestry problem , and my teacher couldn't tell me the answer . He told me to search for it, but I can't find anything about the reaction between Methyl Orange and HCl .. If you could help me , please leave a message at YM : valentin_gr2008@yahoo.com Thanks !
How do you a prepare methyl red indicator?
To prepare methylene blue indicator mix together some methylene blue with a naproxen solution. Then dilute with distilled water. If you would like your mixture to have a deeper blue color then add some juice from boiled cabbage.
How do you standardize a solution of NaOH and what reagents to be used?
If you have a standard solution of an acid, like hydrochloric or sulfuric, you can perform a titration in the presence of phenolphtalein or methyl orange and calculate the solution's normality or, you can weigh a sample of a strong solid acid ( orthoiperiodic acid or even oxalic acid), titrate the acid with the hydroxide solution, again in the presence of phenolphtalein or methyl orange and calculate the concentration of NaOH. If you want to have a solution with an exact concentration, let's say 1 molar, and the actual concentration is 1,33 molar, you simply calculate how much water you need to ad in a specific quantity of solution, to dilute it to exactly 1 molar.
How much 6M NaOH needed to react with methyl salicylate?
To calculate the amount of 6M NaOH needed to react with methyl salicylate, you would first need to know the molar ratio between NaOH and methyl salicylate from the balanced chemical equation of the reaction. Then, you can use the volume or weight of methyl salicylate and the molarity of NaOH to determine the amount needed for complete reaction.
Why does NaOH turns pink when phenolphthalein indicator is added?
Due to the increase of the pressure found within the flame of the bunsen burner, the pressure creates a vacuum thus sucking the phenollphthalein up and turning the solution to the color of the akaline solution.

Why is thymol blue used as the indicator for titration of acetic acid and naoh?
Thymol blue changes color in the pH range of 8.0 to 9.6, making it suitable for titrations involving acetic acid (pKa ~ 4.75) and sodium hydroxide. At the equivalence point of the titration, the pH is around 8.5, which falls within the indicator's color change range, allowing for a sharp color transition at the endpoint.
Why methyl orange is used instead of phenolphthalein in hcl and naoh titration?
This is so since the pH at the end point of Phenolphthalein is 9.1 and methyl orange is 3.7. For a strong acid strong base titration which the end point is between 3-11 phenolphthalein is used
