The ph of the solution after 23.0 ml of HCl have been added to the base is 3.88 M.
Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.
Calculation:-
Given,
C₁ = 0. 2 M
V₁ = 35. 0 ml = 0.035 L
C₂ = 0. 25 M
V₂ = 253. 0 ml = 0.023 L
C₁V₁ + nC₂V₂ = C × total volume
0. 255 × 0.035 + 2×0. 328 × 0.045 L = C × 0.08
C = (0.0089 + 0.0296) / 0.08
= 0.0385 / 0.08
= 0.48 M
Calculation:-
Normality of acid normality of base
= nMV nMV
= 1 × 0. 20 × 0.035 L 1 × 0. 25 ×0.023 L
= 7 × 10⁻³ = 5.75 × 10⁻³
the overall acid will be high
net concentration = 7 × 10⁻³ - 5.75 × 10⁻³
= 1.25 × 10⁻³
pH = -log[1.25 × 10⁻⁴]
= 4 - log 1.25
= 4 - 0.12
= 3.88
The concentration of a substance is the quantity of solute found in a given amount of solution. Concentrations are normally expressed in terms of molarity, defined because of the variety of moles of solute in 1 L of solution.
The Concentration of an answer is a measure of the quantity of solute that has been dissolved in a given amount of solvent or solution. A concentrated answer is one that has a rather huge quantity of dissolved solute.
