A network of two polymers plus sulfuric acid allows a hydrogel to keep its elasticity and softness at extreme temperatures.

An acid and alkali will neutralise each other and produce a salt and water. This is called a neutralisation reaction. The name of the salt produced can be worked out from the names of the acid and ...

If we're looking for life as we don't know it, the best solvent out there may be concentrated sulfuric acid — the stuff that's floating around in the clouds of Venus.

Two new catalyst systems take aim at these problems. One catalyst splits ethanol to give hydrogen at 270 °C and produces ...

Acid Mine Drainage (AMD) happens when polluted water decants from mines and flows over pyrite, which is commonly known as ...

Carbon dioxide reacts with water to produce carbonic acid. The double arrow means that carbonic acid breaks down pretty readily to form carbon dioxide and water again. A hydrogen atom from the ...

This pigment is a natural acid-base indicator. It is blue in neutral substances, like plain water. When an acid like lemon juice gets in the water, a reaction makes the indicator molecule change shape ...
