For an acid-base reaction,1 M Al(OH)S1U1B13S1U1B0 has a normality of 3 N.This is best explained because: September 21, 2022 by 8i9x6 The equivalent mass is three times the molar mass. Each mole contains 3 moles of hydroxide ions that can react with 3 moles of hydrated protons. The mole fraction is equal to 3 when aluminum hydroxide is mixed with water. The normality is always three times stronger than the concentration of a solution. At least two of the above statements are correct. See Answer Each mole contains 3 moles of hydroxide ions that can react with 3 moles of hydrated protons.
