The Amazing Reactions of Sodium and Gallium

🔥Gallium can form alloys with other metals, such as indium, that have lower melting points than gallium itself.

💥Gallium diffusing into the crystal structure of aluminum weakens it, making it easy to break.

❄️Sodium and gallium do not react with each other, even when in contact for an extended period of time.

🌊The reaction between sodium and water is explosive, causing the sodium to catch fire and release sodium hydroxide.

🧪Gallium can create crystal structures within water, forming gallium ice cubes.

Is gallium dangerous to touch?

—No, gallium is not dangerous to touch. It can stain your fingers, but it is safe to handle.

Can gallium weaken other metals besides aluminum?

—Yes, gallium can weaken other metals, but it specifically has a strong effect on aluminum.

Is the reaction between sodium and water dangerous?

—Yes, the reaction between sodium and water is highly reactive and can be explosive. It should only be done under controlled conditions by professionals.

What happens when gallium is mixed with indium?

—When gallium is mixed with indium, it forms an alloy with a lower melting point than gallium itself.

Can sodium and gallium react with each other?

—No, sodium and gallium do not react with each other, even when they are in contact for a long time.
