A. 25.0 ml of a solution of sodium hydroxide solution required 21.50 ml of 0.100 mol/l sulphuric acid for neutralisation.
nexus9112 [7]

The concentration of the sodium hydroxide solution in mol/l is 0.176 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.

Given

V =25 ml = 0.025 L

M = 0.1

C₁ = 0.1

V₁ = 21.50 = 0.022 L

C₂ = ?

V₂ = 25 ml = 0.025 L

C₁V₁ = C₂V₂

C₂ = C₁V₁ / V₂

   = 0.1 * 0.022 * 2 / 0.025

   =  0.176 M

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 answer.

The Concentration of an answer is a measure of the quantity of solute that has been dissolved in a given amount of solvent or answer. A concentrated answer is one that has a rather huge quantity of dissolved solute.
