1:1  10-26[理·化学]秦老师带大家掌握溶液稀释问题中pH的计算
推荐理由：稀释问题中pH的计算时千万注意：电解质溶液稀释到接近中性后不能忽略水的电离！ 讲解人：http://www.jiandan100.cn/teacher/ ，北京市化学高级教师，海淀区青年化学学科带头人，重点中学化学教研组组长。 题面：在25℃时，pH等于2的盐酸溶液稀释到原来的1000倍后， pH等于多少？再稀释1000倍呢？ 本部分内容设定了隐藏,需要回复后才能看到
 跟帖分享你的答案，即可看到正确答案和解析！别忘了回帖后再点进来查看答案哦~如果是碱的稀释呢？自己先思考思考吧 ------------------------------------------------------------------------------------------------------------------------------------------------------------------ 查看更多本年级每周一题，请点击：http://www.jiandan100.cn/bbs/upload/forumdisplay.php?fid=384&
