For each of the following acid-base reactions, calculate how many grams of each acid are necessary to completely react with and neutralize 2.6 g of the base. Part A HCl(aq)+NaOH(aq)→H2O(l)+NaCl(aq)

Answer 1

This is a template with instructions on how to answer:

First determine the base

HCl(aq)+NaOH(aq)→H2O(l)+NaCl(aq)

Acid          Base           water      salt

Given 2.6 g of base

Find: how many g of acid to neutralize the base.

From chemical equation, 1 mole of base reacts with one mole of acid.

Note: The acid and base contain 1 of each type of atom.

Convert 2.6 grams of base to moles:

              Find the amu of the base: (amu = atomic mass units, = grams per mole)

                             Find Na amu =

                             Find O amu =

                             Find H amu =

                             Add to get base amu =

              Calculate moles of base = 2.6 g/(base amu g/mol) = _______ mol base

Mole ratio = 1:1    1 mol base = 1 mol acid

              ______ mol base = _____ mol acid

              Find the amu of the acid

                             Find H amu =

                             Find Cl amu =

                             Add to get acid amu =

              Find the grams acid = ______ mol base X amu _____g/mol = ________ g
