Adding an acid to a solution that already has a base in it is called neutralizing the base. Were you able to return the pink (acidic) and green (basic) indicator solutions back to blue (the control ...

As carbon dioxide is removed from solution, the pH of that solution RISES (the solution becomes less acidic and more basic). If a BTB solution becomes more basic, the solution changes to a blue color ...

How did Earth transform from a hostile, acidic ocean world to one that nurtured life? Scientists at Yale and in Singapore ...

Transparent aluminum oxide (TAlOx), a real material despite its sci-fi name, is incredibly hard and resistant to scratches, ...

Basic substances neutralise acids, resulting in the pH of the acid increasing towards 7, and water being produced. A soluble base dissolves in water to form an alkaline solution. During ...

The pH scale is used to measure how acidic or basic a water-based solution is. A pH value below 7 indicates an acid; and above 7 indicates a base. While the ocean is still basic or alkaline, ...

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 ...

The pH of a solution is a measure of its concentration of hydrogen ions. The higher the concentration of H + ions in an acidic solution, the lower the pH. A pH of 1 represents a hydrogen ion ...
