BCl₃ is Lewis acid, that is an acceptor of electronic couple. Borum accepts electronic couple on the emptiest orbital.
BCl₃ + HCl = H[BCl₄]
BCl₃ + Cl⁻ = [BCl₄]⁻
Lewis base
acid
Answer:
The presence of nitrogen in the organic compound is detected by fusing organic compounds with sodium metal to give sodium cyanide (NaCN) soluble in water. This is converted into sodium ferrocyanide by the addition of sufficient quantities of ferrous sulphate.
Explanation:
It is what I found online.
Answer:
Titration curves for strong and weak acids illustrating the proper choice of acid-base indicator. Any of the three indicators will exhibit a reasonably sharp color change at the equivalence point of the strong acid titration, but only phenolphthalein is suitable for use in the weak acid titration.
Explanation:
Answer:
The original molarity is 1,1030M.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We use the formula for dilutions:
C1 x V1 = C2 x V2
C1= (C2 xV2)/V1
C1= ( 1400 ml x 0,286 M)/363 ml
<em>C1=1,1030 M</em>
Letter B is the most plausible answer :)
