    一开始是氢氧化钠与硫酸反应没有沉淀产生,消耗了2.0gNaOH溶液,硫酸反应完之后,氢氧化钠与硫酸镁反应,开始产生沉淀,至硫酸镁完全反应,不再产生沉淀,根据氢氧化镁的质量求出氢氧化钠的质量为20.0g,当加入NaOH溶液的质量为20.0g+2.0g=22.0g;硫酸镁已完全反应;根据数据可以画出加入4%NaOH溶液质量0—30.0g过程中,产生Mg(OH)2沉淀质量对应的变化如图:


    故答案为:酒精灯;长颈漏斗;
    ; 气密性检查;将导管从水槽中移出;熄灭酒精灯;防止水槽中的水倒流入试管引起试管破裂;
    ;将带火星的木条放于导管口处,若木条复燃则满; ;
    难溶于水;密度比空气小;
    过氧化氢水氧气;
    ;未等导管口气泡连续、均匀冒出就开始收集或集气瓶中未装满水.
    据常用仪器回答;
