When quicklime (calcium oxide, CaO) is added to water, it undergoes an exothermic reaction, producing calcium hydroxide (slaked lime, Ca(OH)₂). The reaction can be summarized as follows: CaO + H₂O → Ca(OH)₂. This process releases heat and results in a highly alkaline solution, which can increase the pH of the water significantly.
What else can I help you with?
Is the water in a swimming pool a mixture or compound?
Water in a swimming pool is compound because the water and chlorine have been chemically combined.
What does the chemically buffered combination of strong acids that dissociate completely in water with weak bases such as hydroxides lead to?
This leads to neutral water by H+ + OH- --> H2O and neutral salt solution when added in equavalent amounts, BUT it is NOT a buffered solution.
Does water and dirt chemically combine to form a compound?
Yeah, mud.
What two elements are chemically combined in a compound?
atoms of hydrogen and oxygen chemically combined to form water
Dissolving salt into water is physical or chemical change?
If you dissolve salt in water you have not changed the materials chemically.
Is the water in a swimming pool a mixture or compound?
Water in a swimming pool is compound because the water and chlorine have been chemically combined.
What happenns wen the wet seoson dose to the everglases?
more water is in the swamp in the everglades that's what happense in the wet seoson in the everglases
Distillation produces water thats?
chemically pure.
Is salt water a mixture?
well since it is salt and water i guess it is a mixture
What is the pH of chemically pure water?
Chemically pure water has a neutral pH of 7 at 25°C.
How can you change water chemically?
add a chemical.
Does water react with diamond?
No, water and diamonds do not react chemically at all.
What is a pure substance that contains three elements that are chemically bond?
One example of a pure substance containing three elements that are chemically bonded is water (H2O). Water is composed of hydrogen and oxygen atoms that are chemically bonded to form the water molecule.
What does the chemically buffered combination of strong acids that dissociate completely in water with weak bases such as hydroxides lead to?
This leads to neutral water by H+ + OH- --> H2O and neutral salt solution when added in equavalent amounts, BUT it is NOT a buffered solution.
Can oil be separated from water chemically?
I dont think it can
What is the chemical reaction for oil and water?
Oil and water do not react chemically; they are immiscible due to differences in polarity. Oil is nonpolar and water is polar, so they do not mix and form separate layers instead.
How does hard water differ chemically from soft water?
Hard water has more calcium than soft water does
