第841章 触动

实验室里有两个人在忙碌，一个正在配置溶液，另外一个则在做着滴定工作。
不管是配置溶液还是滴定工作都是高中化学就学过的，高中里也有过这方面的实验，不过远没有真正实验室里那么严谨，主要是让学生们明白一下是怎么一回事。
“吴教授！”忙碌的两人见吴怡莉带着一个年轻人进来，纷纷抬头叫了下，然后又用好奇的目光打量了葛东旭几眼。
“我介绍一下，这位是葛东旭，环境化学大一新生，今天开始会成为我的实验助手。他们两人都是我的硕士研究生，一个叫郭巴巴，一个叫张梦萱。”吴怡莉介绍道。
大一新生就开始来实验室实习本来就非常稀少，而眼前这位葛东旭不仅大一下半学期就来实验室实习，而且吴怡莉教授还亲自带着他参观实验室，而且听她的意思，以后这个大一新生还不是属于那种给他们这些研究生洗杯子打杂当下手的，而是要当她的实验助手。
大一新生当学科带头人的实验助手！
郭巴巴和张梦萱一想到这个，脸上忍不住就露出了震惊之色，尤其郭巴巴震惊过后，一双看向葛东旭的小眼睛更是闪烁着八卦之光，若不是因为有吴教授在，估计他早已经冲上去拉住葛东旭问个不停了。
“你目前接触的实验少，刚开始可以在这里跟他们一起学着做一些基础实验。”给双方介绍过，又等他们互相打过招呼后，吴怡莉微笑着对葛东旭说道。
“没问题，等会我就可以开始学着跟他们一起做。”葛东旭点头道。
说着，葛东旭朝正在进行滴点实验的张梦萱看去。
此时张梦萱左手抓着滴定管控制着活塞，逐滴往右手抓着的锥形瓶中滴。随着滴定管中的液体滴入锥形瓶，她的右手匀速地摇动着锥形瓶。
“張梦萱正在进行硝酸溶液浓度标定。”郭巴巴显然是个自来熟的人，见葛东旭看向張梦萱，便凑过来解释道。
“用氢氧化钠来标定对吧？”葛东旭化学知识还是很扎实的，郭巴巴一说，他便脱口道。
葛东旭话刚说出口，張梦萱滴定的速度明显慢了下来，当有一滴氢氧化钠溶液滴进锥形瓶时，锥形瓶中本是无色的硝酸溶液突然间变成了粉红色。
看到这一幕，葛东旭突然间浑身一震，两眼精芒暴涨，仿若看到了那锥形瓶中有一颗粉色的丹药在形成。
“酸碱中和，氢离子和氢氧根离子数量相当，酸碱才能完全中和，溶液才达到酸碱度平衡。炼丹不也一样吗？只有五行化气，一阴一阳平衡，方才能成丹，否则阴阳五行失衡，又如何能成丹？我只知道按古配方把药物加入其中，却不知道古配方给的只是大致数量，具体却还需在炼丹时根据阴阳五行变化随时进行增减。就跟这酸碱中和标定一样，是需要逐滴精确地去中和。”葛东旭脑子里如同闪电一般划过，竟然从化学的酸碱中和中想到了天地间的阴阳五行平衡，从而明白他炼丹失败的原因所在。
“东旭你怎么了？”葛东旭正陷入顿悟中时，耳边突然响起吴怡莉关心的声音，心头一惊，回过神来，这才发现吴怡莉正关心地看着他，而郭巴巴和那个张梦萱则像看怪物一样看着他，显然是不明白这家伙怎么好端端的突然两眼发直，整个人变得傻愣愣的。
??今天三更完毕，谢谢支持。
