Among BF₃, NF₃, OH⁻ and ALCl₃ both NF₃ and OH⁻ acts as a lewis base.
Explaination:
According to lewis theory of acid and base, base is a specie which has either lone pair of electrons or is negatively charged. So, in the given compounds Nitrogen trifluoride contain lone pair of electron on nitrogen and Hydroxide contains a negative charge on oxygen. And botha are capable to donate these electrons to a lewis acid (electrophiles).

Yes it is h20 is a strong base
Answer : The correct option is, (A)
Explanation : Given,
pH = 4.33
pH : It is the negative logarithm of hydrogen ion concentration.
First we have to calculate the pOH.
Now we have to calculate the concentration.
Therefore, the concentration is,
Answer:
molarity = moles of solute / volume of solution in liters
Explanation:
