as a cleaning agent. Identifying calcium hydroxide might be a chemistry class assignment that requires two tests. The first one measures the pH (acidity) of the calcium hydroxide solution to ensure it
Kalkwasser is a hobby term for calcium hydroxide Ca(OH)2powder that when mixed with freshwater it creates a solution that will maintain both calcium and alkalinity levels in a reef tank. When Kalkwasser solution is added to saltwater, the CO2in your aquarium water will react with the hydroxid...

Write down a balanced chemical equation for the reaction under investigation. A balanced reaction contains the same number of each type of atom on both sides of the reaction arrow. For example, the reaction between calcium hydroxide, or Ca(OH)2, and hydrochloric acid, or HCl, is represented ...
you can consider using calcium carbonate hydroxide. Also, you should use the copper or PVC water pipes instead of lead ones because they are safer for your overall health. Before using the water running from the water pipes, you should make use of filtration system to remove heavy mental and...
