What else can I help you with?
Is AgCl a precipitate?
YES!!! AgCl forms a WHITE ppt. It is one of the Classic Tests for halogens. AgF = No ppt. AgCl = white ppt. AgBr = cream/pale yellow ppt AgI = strong yellow ppt. AgAs = Not chracterised.
Why wont AgI and AgBr dissolve in NH3?
AgI and AgBr are not as souble as AgCl or AgF so it takes a higher concerntration of NH3 to dissolve it. So that do dissolve in Nh3 but the solution you are using needs to be more concertrated.
Is agcl insoluble in water?
Silver chloride is insoluble in water because the ionic bonds of the salt are too strong to be broken by the dipole interaction with water. Enhancing the salt's ionic integrity is the lattice energy of the ionic interaction.
What type of defect is produced when AgCl is doped with CdCl2?
When AgCl is doped with CdCl2, a Schottky defect is produced. This occurs when an equal number of cations and anions are missing from their lattice sites, leading to the formation of vacancies in the crystal structure.
What happens when you mix AgNO3 and NH3?
When you mix AgNO3 (silver nitrate) and NH3 (ammonia), a white precipitate of AgCl (silver chloride) forms. This reaction is used to test for the presence of chloride ions in a solution, as silver chloride is insoluble in water and will precipitate out.
What is chemical element is used in films and turns black in light?
These are silver halides as AgCl and AgBr.
Why silver hallides are insoluble?
Silver halides, such as silver chloride (AgCl), silver bromide (AgBr), and silver iodide (AgI), are largely insoluble in water due to their strong ionic bonds and the low solubility product constants (Ksp) associated with these compounds. The lattice energy of these salts is high, meaning that a significant amount of energy is required to separate the ions in the solid state. Additionally, the polar nature of water does not provide sufficient energy to overcome this lattice energy, leading to their insolubility in aqueous solutions.

Can silver be mixed with other elements to create something else?
Yes, silver can react with many other elements forming compounds: AgS, AgCl, AgI, AgBr etc.
Is agcl insoluble in water?
Silver chloride is insoluble in water because the ionic bonds of the salt are too strong to be broken by the dipole interaction with water. Enhancing the salt's ionic integrity is the lattice energy of the ionic interaction.

When AgCl is doped with CdCl2, a Schottky defect is produced. This occurs when an equal number of cations and anions are missing from their lattice sites, leading to the formation of vacancies in the crystal structure.
Is KCI plus AgNO3 AgCl plus KNO3 Endothermic or exothermic?
The reaction between KCl and AgNO3 to form AgCl and KNO3 is an exothermic reaction. When these two ionic compounds react, they form a solid precipitate of silver chloride (AgCl) and release energy in the process. This release of energy indicates that the reaction is exothermic.
Why silver halides show frenkel defect?
Silver halides, such as AgCl, AgBr, and AgI, exhibit Frenkel defects due to the small size of silver ions compared to the halide ions. In a Frenkel defect, a cation (in this case, Ag+) is displaced from its lattice position and occupies an interstitial site, creating a vacancy in its original position. This defect is favored because it allows for the accommodation of the smaller silver ions without significantly distorting the crystal lattice. As a result, Frenkel defects enhance the ionic conductivity of silver halides, making them useful in various applications, including photography and as semiconductors.
Discuss the significance of the Ksp of AgCl on the accuracy of the Mohr test?
The solubility product constant (Ksp) of AgCl is crucial in the Mohr test for chloride ions because it determines the maximum concentration of Ag+ ions that can be in solution before AgCl precipitates. A higher Ksp value for AgCl means a higher concentration of Ag+ ions can be present before precipitation, leading to more accurate results in the Mohr test for chloride ions. Conversely, a lower Ksp value could lead to premature precipitation of AgCl, affecting the accuracy of the test.
What happens when you mix AgNO3 and NH3?
When you mix AgNO3 (silver nitrate) and NH3 (ammonia), a white precipitate of AgCl (silver chloride) forms. This reaction is used to test for the presence of chloride ions in a solution, as silver chloride is insoluble in water and will precipitate out.
What is silver's valency?
One is the answer at high school. Silver has a number of valencies:- 1 - the most common, AgCl, AgBr, Ag2O are examples thi is the one to remember! 2 - AgF2 is known 3- Ag2O3 is known
