1. When you press the eyedropper, acid and base are put.
2. Drag the created ions to the desired location. - I want students to look good.
3. Hydrogen ions and hydroxide ions are dragged to collide and become water. - If you compare the hydrogen ion with the hydroxide ion number and drag it with the mouse, it collapses into water. At the moment of change, the heat is shown for a while to express that it is fever.
4. If you change the indicator, you can check the color change according to the liquidity. - You can see the indicator color without changing the indicator at first, and repeat the experiment while changing the indicator color. Or you can make an acid or an alkaline, change the indicator, and try to think about what color it will change.
5. Only the hydrogen ions and hydroxide ions that make the neutralization reaction appear larger. You can reduce the size by tapping Reaction Ion View. To emphasize only neutralizing ions, you can observe hydrogen ions and hydroxide ions by fading the sodium or chlorine ions by hiding the viewer's ions.
6. Up to 6 acids and bases can be put in, and acid and base can not be removed once. You will have to experiment again from the beginning by pressing again. - In the actual experiment, you can not remove the acid or base.
It can be used for explanation of acids or bases, not for neutralization reaction, but also for explanation of indicators.
