已知：\(\rm{2Na[Al(OH)_{4}]+CO_{2}→2Al(OH)_{3}↓+Na_{2}CO_{3}+H_{2}O.}\)向含\(\rm{2molNaOH}\)，\(\rm{1mol}\) \(\rm{Ba(OH)_{2}}\)，\(\rm{2mol}\) \(\rm{Na[Al(OH)_{4}]}\)的混合溶液中慢慢通入\(\rm{CO_{2}}\)，则通入\(\rm{CO_{2}}\)的量和生成沉淀的量关系正确的是\(\rm{(}\) \(\rm{)}\)
| 选项 | \(\rm{A}\) | \(\rm{B}\) | \(\rm{C}\) | \(\rm{D}\) |
| \(\rm{n(CO_{2})(mol)}\) | \(\rm{2}\) | \(\rm{3}\) | \(\rm{4}\) | \(\rm{6}\) |
| \(\rm{n(}\)沉淀\(\rm{)(mol)}\) | \(\rm{1}\) | \(\rm{2}\) | \(\rm{3}\) | \(\rm{3}\) |
