How are precipitation reactions used in forensic work?
Precipitation reactions are used in forensic work to identify the presence of specific ions in a sample. By introducing a reagent that forms a precipitate with the ion of interest, forensic scientists can visually confirm the presence of that ion based on the formation of a solid in the solution. This technique is commonly used in drug analysis, toxicology, and criminal investigations to provide evidence for identifying substances at a crime scene.
What is the formula for a base using the nickel II ion?
The formula for a base using nickel(II) ion is Ni(OH)2. This compound forms when nickel(II) ion (Ni^2+) reacts with hydroxide ion (OH^-) in a 1:2 ratio to produce the basic compound nickel hydroxide.
How can you identify Ammonium?
Ti identify ammonium ion, NaOH is added to the original solution of the ammonium salt and a paper dipped in HCl is brought to mouth of test tube. If white vapours are observed, then ammonium is present. Or Neissler's reagent(K2HgI4) can be added to the original solution of the ammonium salt. A reddish brown ppt. is observed in case of ammonium ion.
What is the ionic formula for nickel II chromate?
The ionic formula for nickel(II) chromate is NiCrO4. This compound is formed by the combination of the nickel ion (Ni2+) and the chromate ion (CrO4 2-).
What is the ionic charge of Nickel in?
it depends what element you have with it but usually its a 2+ ion but it can also be a 3+ ion but its less likely
WHAT IS TEST REAGENT USED TO IDENTIFY NITRATE ION?
A common test for nitrate ion is with diphenylamine.
What is meant by ion pair reagent?
An ion pair reagent is a reagent used in analytical chemistry to facilitate the formation of ionic pairs between a charged analyte and a counterion. It involves the addition of a reagent that can associate with the analyte and form a stable ion pair, which can then be selectively extracted or separated. This technique is commonly used in chromatography and extraction methods for the analysis of charged species.
Which ion is detected by Nessler's reagent?
NH4+ is detected by nessler's reagent.
What is the name of the rection if nickel ii ion react with iron iii ion to get iron ii ion and nickel iii ion?
double decomposition
What is the reagent that will convert benzaldehyde to benzoate ions?
The reagent that will convert benzaldehyde to benzoate ions is a base such as hydroxide ion (OH⁻) in the presence of water. The base deprotonates the aldehyde group of benzaldehyde to form the benzoate ion.
When nickel combines with fluorine to form nickel fluoride the charge of the nickel ion is what?
The answer is Ni3+
What batteries are used in electric cars?
Nickel Metal Hydride or Lithium Ion batteries are the most widely used.

When a solution of a nickel salt was electrolyzed by a current of 0.4a flowing for 965 secs 0.118g of Ni is formed. what is the charge on the nickel ion?
The nickel ion is Ni(2+).
List three types of batteries that might be used on notebooks?
NI-Cad (nickel-cadmium), NiMH (nickel-metal-hydride), and Lithium Ion
What is the formula for nickel(II) ion?
The compound nickel (II) nitride consists of a nickel ion with a +2 charge and a nitride ion with a -3 charge. Since this compound is neutral, the charges must balance. Consequently, it can be determined that the formula of nickel (II) nitride is Ni3N2.
