In the titration to standardize sodium hydroxide, the volumes of NaOH needed to reach the endpoint Describe how on a molecular level the indicator phenolphthalein works in different transitions. Explain why it is quantitatively not acceptable to titrate each of the vinegar s...
If 40.50 mL of 0.0150 M aqueous HI is required to titrate 50.00 mL of an aqueous solution of NaOH to the equivalence point, what is the molarity of the NaOH solution? Step 1:Write the balanced chemical equation for the reaction and identify the titrant and t...
22.30 mL of 0.164 M NaOH is used to titrate 0.283 grams of an unknown acid. What is the molar mass of the acid? How can you determine the concentration of solution after titration? Calculate the mass percent for the solute for the following: a. 50 g of NaOH in 323 g of NaOH b....
How to determine when to reach the equivalent point?Analytical Chemistry:Analytical chemistry is one of the major branches of chemistry which is greatly concerned with instrumentation, sampling, validation of results, qualitative and quantitative analysis. It uses...
I was reading online that the normal appearance of LDA is a light yellow to brownish color. I keep getting solution that is clear or slightly turbid. Whenever my professor does that reaction with me, he tends to get a yellowish color. Why don't you buy it from Aldrich? Titrate it as...

Mills: So is it a goal then to basically titrate the medicine so that you can sort of keep at that hypo level because it's effective? Miklowitz: That's something that's Kay Jamison has written a lot about is she was a psychologist and also a writer. She talked about finding the sor...
I don't say that because.I dislike pharmacology, I say that because in many.cases behavioral tools are not only safer and easier.to titrate to adjust the duration, et cetera.than is pharmacology, but also because.they can sometimes as in the case of.the study we just described for you ...
