scientific reports投稿提交问题求助 Scientific Reports投稿求助

朋友你好，直接往要投的报刊的电子邮箱投稿即可。根据我多年从事文字工作的经验，我认为：如果投稿更有针对性，命中率会更高一些。这就关系到，你是哪里的？干什么的？写的稿件是什么体裁？什么内容？如果说投稿的话，最好投当地的报刊、网络或者是你从事的职业报刊发表，要投哪个媒体首先要研究哪个媒体，看它需要什么内容、什么体裁、什么格式的稿件，“对症下药”，这样会更轻松一些、方便一些，命中率会更高一些。如果你能够告诉我你的具体情况（干什么工作，哪里的，写的小说的大致内容等），我可以给你一些建议。我1993年开始在部队时开始发表各类文章，包括：报告文学、新闻、诗歌、散文、小说、评论等体裁的，到目前，先后在《人民日报》《法制日报》《农民日报》《中国文化报》《法制文萃》《半月谈》《解放军报》《中国国防报》《中国绿色时报》《中国日报》《中国教育报》《人民公安报》《中国交通报》《中国安全生产报》《中国转业军官》《中国人事》《道路交通管理》等报刊发表的大约5000篇左右吧，有40多篇获奖。另外：投稿时，第一要有信心，第二要投对报刊媒体，这两点非常重要。祝你成功！

Purpose



Determine the concentration of acetic acid in vinegar through titration.

Understand the concepts of titration, the tytrant, the analye, and the equivalence point.

Understand the usage of indicators such as phenolphthalein.

Describe the process, techniques, and purpose of titration.

Be able to write a balanced chemical equation representing the stoichiometric equivalence point of a reaction.

Understand how strong and weak acids differ.

Determine the average concentration, molar, and percent concentration of acetic acid in vinegar.



Abstract



To summarize the experiment, in this laboratory exercise we will determine the percentage Acetic Acid (CH3CO2H) in Vinegar. We did this by Titrating the Acetic Acid present with a Strong Base; Sodium Hydroxide (NaOH). The Endpoint of the Titration will be detected using a Phenolphthalein indicator; an acid-base indicator that changes color from clear to pink in going from its acidic form to its basic form.



Materials



Bottle of distilled water

Roll of paper towels

Scissors

Source of top water

Beaker, 100mL, glass

Graduated cylinder 25mL

Safety gloves

10mL sin range titration

Syringe titration

Test tube clamp holder

Phenolphthalein solution

5% Acetic acid

Short stem pipet

Sodium Hydroxide, 0.5 M



Procedure



Put on safety goggles. Set up the tube holder, magnetic stirrer, ring stand.

Pour Sodium Hydroxide into the tirator.

Place the magnetic stirrer under it and place the beaker above the stirrer to collect the Sodium Hydroxide.

After the all the usage of Sodium Hydroxide, pour back more Sodium Hydroxide and wash the beaker. Then record the amount of initial Sodium Hydroxide.

This time slowly drop in Sodium Hydroxide until the indicator reacts completely and turns pink without changing back.

Record final amount of Sodium Hydroxide left and use to get the total amount of Sodium Hydroxide used.

Remove balanced acetic acid, wash aRnd dry beaker.



Data



Table: NaOH titration volume





In addition, after the experiment Ms. B believes that the data are all larger than the expectation. The total usage however should be much lesser than the amount we collected in this table. Thus after the second trail there are no more trails.



Calculations



O(∩_∩)O哈哈~ 这是我的化学Report
有神马问题再问咯
基本上是要按照这样的格式的
最后还得有一个总结
