Students then carry out a second reaction with calcium chloride and baking soda in the universal indicator solution. In this example, students observe the production of both a gas and a solid, a color ...

Carbon dioxide (CO₂), the greenhouse gas fueling climate change, is increasingly shaping our lives. It drives rising seas, ...

These coated structures were then connected to electrochemical circuits as cathodes and immersed in a calcium chloride solution. When carbon dioxide was added to the solution, it underwent ...

An internal silver-silver chloride element, in contact with the internal filling solution, establishes a fixed potential. The ion-selective membrane undergoes ion exchange with calcium in the sample, ...

To calculate this, work out the formula of calcium chloride then add all the mass numbers together. One mole of calcium chloride has a mass of 111 g.

Sodium becomes a positive ion and chlorine becomes a negative ion. The positive and negative ions attract each other and form the ionic compound sodium chloride. One calcium and two chlorine atoms are ...
