a 20.0-ml sample of hydrochloric acid (hcl) is titrated and found to react with 42.6 ml of 0.100 m naoh. what is the molarity of the hydrochloric acid solution?

Sagot :

The molarity of the hydrochloric acid solution in the reaction between NaOH and HCl, 1 mole of NaOH reacts with 1 mole of HCl. 1 NaOH + 1 HCl → 1 NaCl + 1 H2O (Mole ratio of NaOH to HCl is 1:1) • The concentration of the NaOH was 0.1 M, or 0.1 moles/liter.

What is molarity?

Molarity (M) is the quantity of a substance in a given extent of solution. Molarity is described because the quantity of moles of solute consistent with liter of solution. Molarity is likewise known as the molarity of a solution.

Therefore, The molarity of the hydrochloric acid solution in the reaction between NaOH and HCl, 1 mole of NaOH reacts with 1 mole of HCl. 1 NaOH + 1 HCl → 1 NaCl + 1 H2O (Mole ratio of NaOH to HCl is 1:1) • The concentration of the NaOH was 0.1 M, or 0.1 moles/liter.
