What color is ethylene glycol?
greenThe color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool).
A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no longer control rust and scale buildup..
What is the kb of sucrose?
What Mass Of Sucrose (molar Mass =342.30g/mol) Is Contained In 500.0g Of The Solution? Kb=0.512 Degrees Celsius/molalityA) 261 G SucroseB)528 G SucroseC)130 G SucroseD)762g SucroseE)223g Sucrose.
Where can I get ethylene glycol?
Ethylene glycol is found in many household products, including:Antifreeze.Car wash fluids.De-icing products.Detergents.Vehicle brake fluids.Industrial solvents.Paints.Cosmetics.
What is the common name for ethylene glycol?
Ethylene glycolNamesPreferred IUPAC name Ethane-1,2-diolOther names Ethylene glycol 1,2-Ethanediol Ethylene alcohol Hypodicarbonous acid Monoethylene glycol 1,2-DihydroxyethaneIdentifiersCAS Number107-21-160 more rows
What is the kb of glucose?
mole of glucose = wt of glucose/mol wt of glucose= 50/180= 0.28. t2= -4.4 degree cel. here, t1= unknown, t2= 100, i=1(non electrolyte),kb=0.52, m= 2.37 (as Q=1, everything is same). t1= 101.2 degree cel.
What is the van’t Hoff factor of ethylene glycol?
Therefore, for ethanediol, we can say that its van’t Hoff factor is approximately i=1 . As I said before, it would be a freezing point depression, so it makes sense that Tf<0 . so, there you go; the solution was indeed b , tf=−20.1∘C .

What is the kb of NaCl?
What is the boiling point of 1 molal aqueous solution of NaCl (Kb =0.52k molal^-1)? – Quora.
What is the kb value?
Kb is the base dissociation constant. The base dissociation constant is a measure of how completely a base dissociates into its component ions in water. Kb = [B+][OH-]/[BOH]
How do you convert KB to Ka?
Solve the equation for Kb by dividing the Kw by the Ka. You then obtain the equation Kb = Kw / Ka. Put the values from the problem into the equation. For example, for the chloride ion, Kb = 1.0 x 10^-14 / 1.0 x 10^6.
What is the formula for ethylene glycol?
What products contain ethylene glycol?
DESCRIPTION: Ethylene glycol is a useful industrial compound found in many consumer products, including automotive antifreeze, hydraulic brake fluids, some stamp pad inks, ballpoint pens, solvents, paints, plastics, films, and cosmetics; it also is used as a pharmaceutical vehicle.
What is the freezing point of glucose?
146 °CGlucose/Melting point
What does a high KB value mean?
A large Kb value means a base has largely dissociated and indicates a strong base. A small pKb value indicates a strong base, while a large pKb value indicates a weak base.
