What is the kb equation?
For bases, this relationship is shown by the equation Kb = [BH+][OH-] / [B].
The products (conjugate acid and conjugate base) are on top, while the parent base is on the bottom..
What is the unit of KB?
one kilobyteIn the International System of Units (SI) the prefix kilo means 1000 (103); therefore, one kilobyte is 1000 bytes. The unit symbol is kB. This is the definition recommended by the International Electrotechnical Commission (IEC).
What is kb and KF in chemistry?
A solution consists of at least one solute dissolving in a solvent. Molality represents the amount of solute in the solvent. … Use a table to look up the freezing point depression (Kf) or boiling point elevation (Kb) constant for your solvent (See Resources).
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 Molality formula?
molality = moles of solute / mas of solvent (kg) molality = 0.0117 mol / 0.341 kg molality = 0.034 mol/kg. Answer : The molality of the sugar solution is 0.034 mol/kg.
What is KF name?
Potassium fluoride (KF)
What is a KF value?
Kf is called the molal freezing point depression constant and represents how many degrees the freezing point of the solvent will change when 1.00 mole of a nonvolatile nonionizing (nondissociating) solute dissolves in one kilogram of solvent. The table below gives values of Kf for various solvents.
Why is NaCl not NaCl2?
The difference between NaCl and NaCl2 is that NaCl is the chemical formula for sodium chloride while NaCl2 does not exist. This is because, sodium is univalent and chlorine is also univalent, so during chemical combination between the two elements, there’ll be interchanging of the valency.
What is the kb of water?

What is NaCl used for?
Sodium chloride (NaCl), also known as salt, is an essential compound our body uses to: absorb and transport nutrients. maintain blood pressure. maintain the right balance of fluid.
What is KB in chemistry?
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] pKb = -log Kb.
