36.5 grams of hydrochloric acid (HCl) is a 1 N (one normal) solution of HCl. A normal is one gram equivalent of a solute per liter of solution. Since hydrochloric acid is a strong acid that dissociates completely in water, a 1 N solution of HCl would also be 1 N for H+ or Cl- ions for acid-base reactions. Ver mais The easiest way to find normality is from molarity. All you need to know are how many mole of ions dissociate. For example, a 1 M sulfuric acid (H2SO4) is 2 N for acid-base … Ver mais Find the normality of 0.321 g sodium carbonate in a 250 mL solution.
