What happens with phenothalein is placed in Magnesium hydroxide?
Phenolphthalein in a solution containing magnesium hydroxide would remain colorless as it does not change color at a basic pH, where magnesium hydroxide is present. Phenolphthalein changes color in acidic solutions, not basic ones.
What happens when oxygen is put in to lime water?
When oxygen is added to lime water (calcium hydroxide solution), it reacts with the calcium hydroxide to form calcium carbonate. This reaction causes the lime water to turn milky due to the formation of calcium carbonate, which is insoluble and settles out of the solution as a solid.
What happens when you mix sulphuric acid with calcium hydroxide?
When you mix sulphuric acid with calcium hydroxide, a neutralization reaction occurs. Calcium sulfate and water are formed as the products of this reaction. The calcium sulfate is a white insoluble solid that precipitates out of the solution.
What happens when you add water in calcium hydroxide?
When water is added to calcium hydroxide, it undergoes a chemical reaction where the calcium hydroxide dissolves in the water to form a solution called calcium hydroxide solution, also known as lime water. This solution is alkaline in nature and can be used in various applications such as in agriculture, food preparation, and water treatment.
What happens if calcium hydroxide is added to carbonated water?
When calcium hydroxide is added to carbonated water, it reacts with the carbonic acid in the water to form calcium carbonate, water and carbon dioxide gas. This reaction results in a white precipitate forming from the calcium carbonate, which can be seen as a cloudy appearance in the solution.
What happens when you mix calcium hydroxide and phenolphthalein?
When you mix calcium hydroxide and phenolphthalein, the solution will turn pink or magenta in color. This color change indicates that the solution is basic, as calcium hydroxide is a strong base. Phenolphthalein is a pH indicator that changes color in the presence of bases.
What happens with phenothalein is placed in Magnesium hydroxide?
Phenolphthalein in a solution containing magnesium hydroxide would remain colorless as it does not change color at a basic pH, where magnesium hydroxide is present. Phenolphthalein changes color in acidic solutions, not basic ones.
What happens when sodium hydroxide is added dropwise to solution containg phenolphthalein?
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will gradually turn pink as the pH increases. This color change is due to the phenolphthalein molecule shifting from its colorless form in acidic conditions to its pink form in basic conditions.
What happens when oxygen is put in to lime water?
When oxygen is added to lime water (calcium hydroxide solution), it reacts with the calcium hydroxide to form calcium carbonate. This reaction causes the lime water to turn milky due to the formation of calcium carbonate, which is insoluble and settles out of the solution as a solid.

What happens when you mix Sodium hydroxide and phenolphthalein?
When you mix sodium hydroxide and phenolphthalein, you will observe a color change. Phenolphthalein is commonly used as a pH indicator, turning pink in basic solutions (such as sodium hydroxide) and colorless in acidic solutions. This color change is a result of the chemical reaction between the sodium hydroxide and phenolphthalein molecules.

Mix calcium oxide with water and then what happens?
Well, The chemical reaction when calcium is placed with water is a fizzing. It fizzes and also "produces" heat. Not sure what the chemical formula would be called however. Calcium Hydroxide possibly
What happens when calcium oxide dissolves in water?
When calcium oxide dissolves in water, it forms calcium hydroxide. This process releases a large amount of heat, making it an exothermic reaction. Calcium hydroxide solution is alkaline in nature and can be used in various applications such as in the production of cement and in agriculture as a soil amendment.
Is there any difference in lime water and slaked lime . If any why do you use different name?
Yes, there is a difference. Slaked lime is the term used to refer to solid calcium hydroxide, and lime water is a calcium hydroxide solution. Admittedly, two distinct terms seems like overkill, but it happens a lot... for example, "salt" and "brine" is essentially the same situation. The terms are historical, and most chemists would just say "calcium hydroxide" and "calcium hydroxide solution" instead.
What happens when sodium hydroxide solution is added to calcium carbonate and then warmed?
CaCO3(s)+2NaOH(aq)--->Ca(OH)2(aq)+Na2CO3(aq) When you heat it later, the water in the solution evaporates leaving you with just the salts. Also, it is better to say, calcium carbonate is added to sodium hydroxide solution as you add a solid to a solution not really vice versa.
