When ammonium chloride mixes with water the solution formed feels cold what type of reaction is this endothermic or exothermic?
When ammonium chloride dissolves in water, it is not a reaction at all, but only a dissolution. Since the solution formed feels cold, the dissolution is endothermic, absorbing heat from its surroundings.
How NH4 NO2 NO3 effect pH in water?
When ammonium nitrite (NH4NO2) dissolves in water, it forms nitrite (NO2-) ions and ammonium (NH4+) ions, which can be slightly acidic due to the release of hydrogen ions (H+). On the other hand, nitrate (NO3-) ions from ammonium nitrate (NH4NO3) do not have a significant impact on water pH as they are neutral. Overall, the net effect on water pH will depend on the relative amounts and concentrations of these ions present.
What will happen when sodium chloride is added to solution of weak acid?
When sodium chloride is added to a solution of a weak acid, the chloride ions from the salt will not react with the weak acid. However, the sodium ions can react with the weak acid to form a salt of the weak acid and a strong acid. This reaction can change the pH of the solution, depending on the relative strengths of the weak acid and the strong acid formed.
How do you prepare cupric chloride solution?
To prepare cupric chloride solution, dissolve copper chloride powder in water by stirring until fully dissolved. The concentration of the solution can be adjusted by changing the amount of copper chloride powder used relative to the volume of water. Always wear appropriate personal protective equipment and handle the chemical in a well-ventilated area.
Cobalt chloride paper test?
The cobalt chloride paper test is a simple test used to detect the presence of moisture in a given sample. When it comes into contact with water, cobalt chloride changes color from blue to pink. This paper test is commonly used in science experiments and as a qualitative indicator for water in various substances.

What can you say about the relative magnitudes of the lattice energy of lithium iodide and its heat of hydration?
The lattice energy of lithium iodide is typically larger than its heat of hydration. This means that more energy is required to break the ionic bonds in the solid lattice of lithium iodide than is released when the ions are hydrated in solution.
What is the relative molecular mass ammonium?
The ammonium ion has one nitrogen atom and four hydrogen atoms. Their atomic masses are 14 and 1 respectively. Therefore the RMM of the ammonium ion s 14+4x1=18.
What is the relative order of freezing points of these three substances... I. Water II. 0.1 M aqueous ammonia solution III. 0.1 M aqueous ammonium chloride?
I believe it's III II then I because of the molar masses for each of them. from highest to lowest freezing points. Also keep in mind of the LD forces, ionic forces, Lattice energyetc. to figure out the bond strength. I hope that right!
What instrument measures relative humidity using the electrical conductance of the chemical lithium chloride?
A hygrometer that uses a lithium chloride sensor measures relative humidity by sensing changes in electrical conductance. As humidity levels change, the conductivity of the lithium chloride sensor varies, allowing for the calculation of relative humidity based on these changes.
What is the relative strength of sodium chloride?
This the sum of concentrations of Cl- and Na+ ions in a given solution of NaCl.
What has the author Pentti Olavi Ilmari Virtanen written?
Pentti Olavi Ilmari Virtanen has written: 'Relative rates of the aluminium chloride-catalysed reactions of methylbenzenes with 3-chloropropionyl chloride in ethylene dichloride' -- subject(s): Aluminum chloride, Chemical kinetics, Chloropropionyl chloride, Toluene
How can the relative magnitudes of the field in different regions be determined from an electric field line diagram?
The relative magnitudes of the field in different regions can be determined from an electric field line diagram by looking at the spacing between the field lines. Regions with field lines that are closer together represent stronger electric fields, while regions with field lines that are farther apart represent weaker electric fields. The density of field lines can give an indication of the relative magnitude of the electric field strength.
Why is the relative atomic mass of chloride not a whole number?
Because relitive atomic masses are NEVER whole numbers.
Why aqua regia don't react with silver?
silver chloride forms, which is insoluble in aqua regia, HCl, or HNO3. silver chloride is soluble in ammonium solutions but this can become very dangerous, as fulminate forms and can detonate when dried, acidifying them with HCl to precipitate the silver and form ammonium chloride solution is a safe way to handle them. insolubility of silver chloride in aqua regia is one reason karat gold is inquatered, and parted in nitric before dissolving gold in aqua regia, the insoluble silver chloride will crust over the gold (from silver in the karat gold), and aqua regia cannot dissolve the gold with an layer of silver chloride protecting the gold from the acids. some small amounts of silver chloride is soluble in aqua regia, remember soluble, or insoluble are relative terms, and can be affected by temperature, PH and so on. metal refiner Richard B.
What is the definition of pie chart?
As per the dictionary, a circular chart cut by radii into segments illustrating relative magnitudes or frequencies -called also circle graph. See the related link for verification.
Is ammonia acidic or basic?
Ammonia is a base. When ammonia (which has a chemical formula of NH3) dissolves in water (chemical formula H2O) it forms a solution of ammonium hydroxide (NH4OH). Ammonium hydroxide is a chemical relative of other bases like sodium hydroxide (lye).
