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 ...

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, ...

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 ...

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 basic, bicarbonate of soda ... It is the ratio of hydrogen ions to hydroxide ions that determine the how acidic a solution is. Now, the colour of Flavin (found in the cabbage) is entirely ...
