discussion for the titration of NaOH and HNO3 by using phenolphthalein & methyl orange indicators
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 a solution that contains 10.0g of NaOH in 400.0 ml of NaOH of solution?
The answer is 0,625 moles.
What is the molarity of 32.0 of NaOH in 450 of NaOH solution?
I assume you mean 32.0 grams of NaOH and 450 milliliters of NaOH. Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters ) get moles of NaOH 32.0 grams NaOH (1 mole NaOH/39.998 grams) = 0.800 moles NaOH Molarity = 0.800 moles NaOH/0.450 liters = 1.78 Molar NaOH
How many grams of NaOH are in 350 mL of a 5.7 M NaOH solution?
Molarity = moles of solute/Liters of solution. ( 350 ml = 0.350 Liters ) 5.7 M NaOH = moles NaOH/0.350 Liters = 1.995 moles NaOH (39.998 grams/1 mole NaOH) = 78 grams NaOH needed ------------------------------------
Which indicator is used in titration of naoh and h2so4?
Methyl orange
Can you use indicator other than phenolphthalein in the titration of NaOH?
Yes you can use methyl red, methyl orange, bromophenol blue and other indicators instead of phenolphthalein in the acid-base titration of NaOH.
Why is thymol blue used as the indicator for titration of acetic acid and naoh?
An indicator that changes its colour around pH value 5 should be used in this titration. Alternatively, instead of Thymol Blue, Methyl Orange or Methyl Red may be used.
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 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 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.

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
How much 6M NaOH needed to react with methyl salicylate?
5 mL of NaOH
Is sodium hydroxide a base or acid how will you justify?
Adding an acid base indicator to a sodium hydroxide solution can verify that it is an alkaline solution. For example, phenolphthalein turns pink in an NaOH solution.
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.
Color change in hcl plus naoh equals nacl plus H2O?
The products are the chemicals that result from the reaction, NACl and H20 (salt and water).The reactants are the checmicals that are combined: HCl and NaOH (hydrochloric acid and sodium hydroxide).
