Question
Titration of 25.0 mL of an HCl solution of unknown concentration requires 14.8 mL of 0.100 M NaOH. What is the molar concentration of the HCl solution?NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)
Solution 1
Sure, here are the steps to find the molar concentration of the HCl solution:
-
First, we need to find the moles of NaOH used in the titration. We can do this using the formula: moles = volume (in liters) x molarity. So, moles of NaOH = 0.0148 L x 0.100 M = 0.00148 mol.
-
From the balanced chemical equation, we know that the reaction between NaOH and HCl is a 1:1 ratio. This means that the moles of HCl will be the same as the moles of NaOH. So, moles of HCl = 0.00148 mol.
-
Finally, we can find the molar concentration of the HCl solution using the formula: molarity = moles/volume (in liters). So, molarity of HCl = 0.00148 mol / 0.025 L = 0.0592 M.
Therefore, the molar concentration of the HCl solution is 0.0592 M.
Solution 2
Sure, here is the step by step solution:
-
First, we need to calculate the moles of NaOH used in the reaction. We can do this using the formula: moles = volume (in L) x molarity. So, moles of NaOH = 0.0148 L x 0.100 mol/L = 0.00148 mol.
-
From the balanced chemical equation, we know that the reaction between NaOH and HCl is a 1:1 ratio. This means that the moles of HCl in our solution is also 0.00148 mol.
-
Finally, we can find the molarity of the HCl solution using the formula: molarity = moles/volume (in L). So, molarity of HCl = 0.00148 mol / 0.025 L = 0.0592 M.
So, the molar concentration of the HCl solution is 0.0592 M.
