説明

Chemistry experiments on your smartphones.

You can Mix chemicals to see how they react, Burn salts to colorful flames and Heat elements to see what colors it emits

There are 150 plus chemicals available to experiment with and more than 750 unique experiment simulations.

Key Highlights

- Adjusting the concentration and quantity of the reactants.

- Regulate the temperature of the reaction.

- Modify temperatures in precipitation reactions and see the effect of temperatures on solubility.

- Slow down / Fast forward time.

- Check the PH and PH change in a reaction, using Indicators.

- Ignite flammable gases formed during reaction.

Disclaimer

Some reactions you will be doing in Unreal Chemist are extremely dangerous and may cause serious injury if conducted in real word.

Even though most of the reactions are accurate to the real world, some reactions may be theoretical since physical verification of some reactions are not completed as of now.

面白い！　けどちょっと惜しい…

化学オタクである私が、1日遊んでみての感想です。まず、無料の割にはちゃんとしていて面白いです。基本的な酸・塩基、塩、単体はあるので、それなりの実験は楽しめます。
良いアプリであるのには違いないのですが、その分、高校化学で習うような物質や反応が一部対応していないのが残念です。具体的には、
・硫化水素
・酸化物や硫化物
・次亜塩素酸塩
・KMnO₄、K₂Cr₂O₇といった強力な酸化剤
・気体として、NH₃、CO₂、Cl₂などがほしい
・KSCNやK₄[Fe(CN)₆]、K₃[Fe(CN)₆]といった鉄イオンの検出試薬
・HFをビーカーに入れても溶けない
・ヨウ素を加熱しても昇華しない
・銅が希硫酸に溶け、水素を発生させている（熱濃硫酸、かつ発生するのは二酸化硫黄でなければならないのに）
・CrO₄²⁻とCr₂O₇²⁻との平衡が成り立たない（K₂CrO₄を硫酸酸性にしてもK₂Cr₂O₇にならない）
・錯イオン生成反応に対応していない
・その他、一部の弱酸遊離反応、酸化還元反応、沈澱生成反応が起こらない

ひとまず、こんなもんでしょうか。ここを改善してもらえると、高校化学の補助教材としても使えるアプリになるのかなと思います。この点で星一つ減点しました。

Dear developers This app is very wonderful, but I think there are room for improvement. After using this app for a day, my impression is that it is decent and interesting for free. It has basic acids, bases, salts, and elements, so I could enjoy some experiments, and I think it's a good app.
However, it is regrettable that some substances and reactions that are learned in high school chemistry in Japan are not supported. For example, I want:
・H₂S
・oxides and sulfides
・hypochlorite
・strong oxidizers such as KMnO₄ or K₂Cr₂O₇
・gases such as NH₃ (not NH₄OH), CO₂ (not H₂CO₃), or Cl₂
・KSCN, K₄[Fe(CN)₆], or K₃[Fe(CN)₆]
・it to react with beaker (glass) when HF is added
・I₂ to sublimate when heated
・Cu no to dissolve in dil.H₂SO₄ (since it must be dissolved in hot conc.H₂SO₄).
・the equilibrium between CrO₄²⁻ and Cr₂O₇²⁻ (K₂CrO₄ does not become K₂Cr₂O₇ when K₂CrO₄ is acidified).
・you to deal with some other complex ion formation reactions (such as [Cu(NH₃)₄]²⁺), weak acid release reactions, oxidation-reduction reactions, and precipitation formation reactions

I think this is all I can come up with for now. I think it would be a much better app that could be used as a supplement to high school chemistry, if you could improve this part.
