（4）问题与交流：由于氧气在水中的溶解度比氢气略大，所以电解刚开始时，正、负极收集到气体的体积比略小于1:2，但随着反应的进行，正、负极收集到气体的体积比越来越接近1:2，原因可能是 。
【答案】（1）
（2）a a管尖嘴处气体燃烧，火焰呈淡蓝色，b管尖嘴处木条燃烧更旺盛
（3）氧元素和氢元素
（4）氧气在水中的溶解达到饱和
【解析】（1）水电解生成氢气和氧气，反应的化学方程式为，故填：；
（2）电解水实验中“正氧负氢，氢二氧一”，则a管中生成的是氢气，b管中生成的是氧气，则实验现象：两玻璃管内都有气泡产生，且玻璃管a中产生气泡的速率更快。一段时间后，将燃着的木条分别放到两个玻璃管尖嘴口处，观察到a管尖嘴处气体燃烧，火焰呈淡蓝色，b管尖嘴处木条燃烧更旺盛，故填：a；a管尖嘴处气体燃烧，火焰呈淡蓝色，b管尖嘴处木条燃烧更旺盛；
