Yes.
Phenolphthalein can be used as an indicator for the titration of a weak acid (oxalic acid) against strong base (sodium hydroxide).

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.
Best indicator for lactic acid when titrated against standard NaOH?
phenolphthalein.
Is methyl orange the indicator used in the titration of na2co3 against hcl solution?
yes it is
Radiometric titration of 110AgNO3 against KCl?
Radiometric titration is "regular" titration, but with the incorporation of a radioactive indicator to monitor the end-point. And that's right from the IUPAC Compendium of Chemical Terminology. If...
Which indicator is suitable for the titration of washing soda against HCL and why?
iv done the titration and the preferred indicator for such a solution is phenalphaline, use a few drops to make it go a bright luminous pink and titrate till clear, not 'cloudy'

What indicator will be used in standardization of sulfuric acid against sodium carbonate?
In this experiment, methyl orange is used because: Its end point matching the equivalent point of the acid-base titration.

What can affect purity of aspirin?
Firstly place 100 to 150 mg of aspirin into a 125 ml conical flask. Next proceed to mix in 15 ml of 95% ethanol solution and add 2 drops of phenolphthalein indicator. Then use the titration method to mix this solution against a standard solution of sodium hydroxide from a burette. Using the value obtained from the titration calculate the molarity of the aspirin. Then calculate the ratio of the observed molarity of aspirin with its theoretical molarity and finally multiply this ratio with 100 to obtain the percentage purity of the aspirin sample.
What are the best indicator use in titration of weak base against strong acid?
vodka cruisers, the raspberry one.
What indicator in titration of sodium carbonate solution against hydrochloric acid would give a complete neutralization?
Litmus paper
What is the principle of BOD?
when magnesium sulfate and potassium hydroxide is added,magnesium hydroxide is formed and precipitates and conc H2SO4 is added and in presence of oxygen the preciptate turns brown color which can be measured by idoine and starch indicator titrated against sodium thiosulfate
What tool can test the acidity of a liquid?
first take 200ml of the sample.then add 1 drop phenolphthalein indicator .titrate against .1 N NaoH
Why do you titrate strong base against weak acid using phenolphthalein?
A strong base and weak acid gives a basic salt. Therefore the end point of a titration between a strong base and a weak base has a pH value above than 7.0 at 298K. As the end point of phenolphthalein is around 9.1 (~can vary between the values of 8.1 to 10.1) at this temperature, it would give more accurate results.
