oblicz ile g. NaOH potrzeba do zobojetnienia 49g H 2małeSO 4małe

M(NaOH)=40g/mol M(H2SO4)=98g/mol 2NaOH + H2SO4= 2H2O + Na2SO4 2*40g/mol(NaOH) ------98g/mol(H2SO4) xg(NaOH) ------49g(H2SO4) x=40gNaOH

M(NaOH)=40g/mol M(H2SO4)=98g/mol 2NaOH + H₂SO₄= 2H₂O + Na₂SO₄ 2*40g/mol(NaOH) 98g/mol(H₂SO₄) xg(NaOH) - 49g(H₂SO₄) x=40gNaOH
