Do a log-log of your sample values (y-axis; e.g., sorption levels), and plot that against the x-axis (e.g., concentration in solution). This will linearize your model so that you can get a regression equation (excel will do this). Use this equation to find the y-intercept. The inverse log-log of your y-intercept gives you your Kf.

Kb= 1/Kf (:
It is defined aste depression in freezing point of solution containing non-volatile solute.wen molality is equal to 1 and is caled molal depression constant i.e. Tf=kf . m
The molarity of KF solution containing 116 g of KF in 1.00 L is 2.00 moles.
What is the chemical composition of kf reagent
dt = kf(im) 0.225 = kf(2(0.100m) 0.225 = kf(0.2) 0.225/0.2 = [kf(0.2)]/0.2 1.125 = kf
Kb= 1/Kf (:
Kf stands for the freezing point constant of the solvent.
2.38 K.kg.mol-1
To calculate the Karl Fischer factor there are three factors that are required. The ml KF reagent used for sample, the factor mg H20/ml KF reagent and the weight in grams.
The alphabet!The corret answer is alpha,beta,chi,delta,epsilon, gama,iota,kapa,lamdamunuomeaga pi sigma theta or tau and zeda
The definition of 0.175 m KF is that 1 kg of water contains 0.175 moles of KF. Thus, 347 g of water is equivalent to 0.347 kg, and to find moles of KF, you calculate as follows:0.175 moles/Kg x 0.347 kg = 0.0607 moles of KF are present (3 significant figures).
The KF is greater than the sum of its partsOwnership of the KF is dispersedPower in the KF flows down…and upThe KF is held together by reputation, not controlThe KF runs on information technologyThe KF is a business
If log(Kf) = 5.167 then Kf = 105.167 = 146,983 (approx).
It is defined aste depression in freezing point of solution containing non-volatile solute.wen molality is equal to 1 and is caled molal depression constant i.e. Tf=kf . m
The molarity of KF solution containing 116 g of KF in 1.00 L is 2.00 moles.
The compound KF is ionically bonded.
KF Çlirimi was created in 1988.
