In chemistry, a solution is made up of a solvent and a solute. The solvent is a substance, usually, a liquid, into which the solute, often a solid or a liquid, is dissolved. An example of a solution is when salt is dissolved in water. The salt is the solute, and the water is ...
Hard water is water that contains high amounts ofCa2+and/orMg2+. Sometimes Mn2+and other multivalent cations are included in the measure of hardness. Note water may contain minerals and yet not be considered hard, by this definition. Hard water occurs naturally under the condition where water ...
Which ions cause hardness of water? Which is a substance that is made up of only one type of atom? What is the molecular mass of a water molecule? What chemical element is P? What is the compound for salt? What are substances called whose water solutions conduct electricity?
and with a multitude of attributes. For example, if we stand on the shore and look at the sea, we see the water, the waves breaking, the foam, the sloshing motion of the water, the sound, the air, the winds and the clouds, the sun and the blue sky, and light; there is sand a...
What is chemistry? History of chemistry Chemistry is a science that tries to understand the properties of substances and the changes that substances undergo. It is concerned with the substances that occur in nature-the minerals of the earth,the gases of the air,the water and salts of the ...
What is feldspars hardness? What is stiffness in biomechanics? Define temporary hardness of water How hard is actinium? What are the properties of hassium? What does it mean for a material to be brittle? What is turgid, flaccid, and plasmolyzed?
Temporary hardness of water is due to the presence of soluble bicarbonates of magnesium and calcium. By heating / boiling, these salts decomposed into insoluble carbonate and hydroxide, respectively. The resulting precipitates can be removed by filtratio
