What else can I help you with?
Which is more concentrated HCl or NaOH?
NaOH.because hcl its a gas.and if we search in lab or merck index we find it in 37 pecenent.also HCl after a period decrease their percent because is said that its gas & afte a short time its release in envirmen. sorry my own language is not english.ican not say what i want.
Would the calculated molar mass be too high or too low if your standardized NaOH were exposed to the air for a long period of time after the standardization?
The calculated molar mass would be too high if the standardized NaOH were exposed to air for a long time. This is because NaOH absorbs carbon dioxide from the air, creating sodium carbonate (Na2CO3). This would make the solution more concentrated and lead to a higher-than-actual molar mass determination.
Is methoxyphenol soluble in NaOH?
Methoxyphenol is a phenol derivative and so, is soluble in water. This means that methoxyphenol will dissolve in an aqueous NaOH solution, but will not react with the NaOH.
Why do you use ethanolic NaOH instead of aq NaOH in titration?
Ethanolic NaOH is used instead of aqueous NaOH in titration to avoid side reactions with water and reduce error in the titration process. The absence of water in ethanolic NaOH helps maintain the concentration and stability of the solution, resulting in more accurate and precise titration results.
Why is NaOH added to water and not the other way?
NaOH is added to water because it is highly exothermic, meaning it releases a significant amount of heat when it dissolves. Adding NaOH to water allows for better control of the heat generated and prevents splattering or boiling of the solution. Additionally, mixing NaOH with water allows the ions to disperse more evenly, resulting in a more homogeneous solution.

What will happen to the molarity of NaOH If a drop of NaOH falls out of the flask during the titration?
You have to realise that a drop from the burette for instance is insignificant, if you are dealing with at least 10ml solution which you usually deal with on a titration. If you don't want to regard it as insignificant, then if NaOH is in the burette, then the solution doesn't become more concentrated with NaOH because that drop escaped.
Is wealth concentrated or more evenly spread out Algeria?
It is less concentrated than in the USA, but more concentrated than in Europe.
Is wealth concentrated or more evenly spread out in Russia?
concentrated

The net flow of molecules from less concentrated to more concentrated solutions is?
Osmosis
Are aliphatic or aromatic aldehydes more soluble in naoh?
yes
Does ADH favor the formation of dilute or concentrated urine?
ADH causes an increase in water reabsorption in the kidneys. Thus, by absorbing more water, the urine becomes MORE concentrated (more compounds in less water = more concentrated)

How can one make urine more concentrated?
To make urine more concentrated, drink less water and consume foods high in salt and protein. This will reduce the amount of water in the body, leading to more concentrated urine.
