Answer:
Explanation:
Citric acid is a tribasic acid , having three ionizable hydrogen in them.
Let the molarity of citric acid be X .
Normality = 3 X
Using the formula S₁ V₁ = S₂ V₂
.4776 M x 16.25 mL = 10 mL x 3 X
X = .2587
Hence molarity of citric acid is 0.2587 M .

Answer:
The electron pair geometry is Trigonal planar
Molecular geometry - Bent
Approximate bond angle - <120°
Explanation:
The valence shell electron pair repulsion theory enables us to predict the shapes of molecules based on the number of electron pairs present on the valence shell of the central atom and based on the hybridization state of the central atom.
sp2 hybridization corresponds to trigonal planar geometry. Let us recall that the presence of lone pairs causes a deviation of the molecular geometry from the expected geometry based on the number of electron pairs.
Hence, owing to one lone pair present, the observed molecular geometry is bent.
