What else can I help you with?
Which phase will be on top in an immiscible mixture of methylene chloride and 1M of sodium hydroxide?
Sodium hydroxide solution will be on the top.
What is slaked lime made from?
Soda lime is a mixture containing principally of calcium hydroxide and sodium hydroxide. Soda lime absorbs carbon dioxide.
What is a mixture containing small undissolved particles that do not settle out?
A colloid is a mixture containing small undissolved particles that do not settle out. Examples of colloids include milk, fog, and gelatin.
What is a mixture contaning small undissolved particles that do not settle out?
A colloid is a mixture containing small undissolved particles that do not settle out. Examples include milk, gelatin, and fog.
What would you see when water is added drop by drop to cold calcium oxide?
When water is added drop by drop to cold calcium oxide (CaO), a vigorous exothermic reaction occurs, producing calcium hydroxide (Ca(OH)₂) and releasing heat. Initially, you might see the calcium oxide fuming or bubbling as it reacts with water, creating a slaked lime paste. The reaction can produce steam, and the temperature of the mixture will increase significantly due to the heat generated. Eventually, you would observe a thick, milky solution of calcium hydroxide forming.
Is lime water a homogeneous mixture?
Yes, lime water is considered a homogeneous mixture. It is made by dissolving calcium hydroxide (lime) in water, resulting in a uniform solution where the particles are evenly distributed and not visible to the naked eye.
What is calcium hydroxide a element or a compound?
A compound is a mixture of elements. As the name implies, CH (or calcium hydroxide) is made up of calcium and hydrogen. Calcium and Hydrogen are elements. Thus, calcium hydroxide is a compound.
Is sodium hydroxide a compound or solution or mixture?
mixture *********************** No, it's a compound.
What is the difference of soda lime and lime water?
Soda lime is a mixture of calcium hydroxide with sodium or potassium hydroxide used as a desiccant in laboratories, while lime water is a saturated solution of calcium hydroxide in water used to test for carbon dioxide gas by forming a white precipitate of calcium carbonate. The main difference is in their composition and intended uses.
Is adding calcium to water a mixture or a compound?
When you add calcium to water, it forms calcium ions (Ca2+) in the water. This results in a mixture of calcium ions in water. The calcium ions and water molecules remain separate entities rather than bonding to form a compound.
When Litmus paper when added to calcium oxide and water?
When litmus paper is added to calcium oxide and water, it will turn blue due to the formation of calcium hydroxide, which is a basic solution. Calcium oxide reacts with water to form calcium hydroxide, releasing heat in the process.
What salt is formed when a solution of calcium hydroxide Ca is neutralized by hydrochloric acid HC1?
the salt formed when a solution of calcium hydroxide is neutralized by hydrochloric acid is calcium chloride. The formula for the calcium chloride formed is CaCl2. Other product formed will be hydrogen gas(H2) and water (H2O). This is because when an acid is neutralized by a hydroxide solution the resultant product should be a salt of the constituent metal(in our case, calcium), hydrogen gas, and water. The water will however not be formed if the mixture is only between a metal in the form of a solid and an acid; in this case only the salt and hydrogen gas are formed.
What is a mixture with small undissolved particles that do not settle out?
A suspension is a mixture with small undissolved particles that do not settle out. These particles are typically visible to the naked eye and can be separated from the liquid by filtration. Examples include muddy water and Italian salad dressing.
Which phase will be on top in an immiscible mixture of methylene chloride and 1M of sodium hydroxide?
Sodium hydroxide solution will be on the top.
What is the difference between soda lime and lime soda?
Soda lime is a mixture of sodium hydroxide and calcium hydroxide used to absorb carbon dioxide. Lime soda is a solution of lime (calcium hydroxide) and soda (sodium carbonate), often used in water treatment to soften water by precipitating calcium and magnesium ions.
What is the molecular formula for lime water?
the chemical name of limewater is saturated calcium hydroxide.
Is solution of sodium hydroxide a mixture?
yes, it is a homogeneous mixture. i had a lab packet for chemistry due the other day and we went over it and this was a very similar question. it showed 4 pictures and we had to pick the homogeneous mixture in the previous illustrations.
