What is hypo solution used in chemistry for iodometric titration?
hypo solution used in iodometric titration is sodiumthiosulphate. Its N\10 normality of Na2S2O3.
How is the KB of ammonia calculated from the half titration point?
At half titration pH=pKa (you need the pH from the graph of your titration, y axis) ph = pKa + log (base/acid) 10^-pKa = Ka Kw=Ka*Kb Kb=Kw/Ka Ka = Kw/Kb
How do you determine ka from a titration curve?
Assuming you know how to find the equivalence point on the titration curve, and assuming it is not [strong acid/strong base] or [weak acid/weak base], all you need to do is find the half equivalence point, which gives you the pKa of the first solution. Then to get the Ka, you go 10-pKa .
What is argentimetric titration?
In analytical chemistry, argentometry is a type of titration involving the silver(I) ion. Typically, it is used to determine the amount of chloride present in a sample. The sample solution is titrated against a solution of silver nitrate of known concentration. Chloride ions react with silver(I) ions to give the insoluble silver chloride:Cl− (aq) + Ag+ (aq) → AgCl (s) (Ksp = 1.70 × 10−10)
What is the colour change in the titration of NaOH and C2H2O4 if using phenolphthalein as an indicator?
Adding NaOH-sol'n to oxalic acid, C2H2O4, the colour (from colorless) has to become purple-blue at pH 8 to 10.
What is the need for an ammonical buffer solution in the determination of hardness of water by edta titration?
during the complexometric titration using edta it is very necessary to maintain the ph of the solution near about 10 so we use ammonium chloride buffer if we will not use this buffer dring the titration ph of sol. will ho lower side
What is hypo solution used in chemistry for iodometric titration?
hypo solution used in iodometric titration is sodiumthiosulphate. Its N\10 normality of Na2S2O3.
3.9L dodge Dakota timing setting?
10 degrees before top dead center. only the 87-91 can be adjusted. the92 and up are not adjustible
How is the KB of ammonia calculated from the half titration point?
At half titration pH=pKa (you need the pH from the graph of your titration, y axis) ph = pKa + log (base/acid) 10^-pKa = Ka Kw=Ka*Kb Kb=Kw/Ka Ka = Kw/Kb
Are prescription sunglasses tax deductible?
Yes, as part of your medical deductions on Schedule A of your return. Depending on your age, you will have to deduct 7.5% or 10% of your Adjusted Gross Income before medical expenses goes on your Schedule A.
What is beta adjusted exposure?
Say $10MM holding of 10 stocks, with beta (to S&P500) 0.90. Then beta adjusted exposure (to S&P500 as the benchmark market) is $9MM.
Which indicator is used for titration of C2H2O4 with NaOH?
Phenolphtalein change colorless at pH < 8 to purple blue at pH > 8 to 10
Can the clutch of the Chevy S-10 be adjusted?
The clutch is hydraulically operated and self adjusts automatically.
How do you set timing on a Chevy S-10 PIckup 2.2 ltr?
You don't. The timing is adjusted thru the ECM.
How do you determine ka from a titration curve?
Assuming you know how to find the equivalence point on the titration curve, and assuming it is not [strong acid/strong base] or [weak acid/weak base], all you need to do is find the half equivalence point, which gives you the pKa of the first solution. Then to get the Ka, you go 10-pKa .

How long is the Valeo Speed Jump Rope?
The Valeo Speed Jump Rope is 10 feet long, but may be adjusted for length.
