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 colour is obtained on adding KSCN reagent to ferric ion solution?
Intense Red Colour
What is the chemical formula for nickel iii and phosphate?
the formula is Ni3(PO4)2 :) The correct answer is Ni PO4, the answer shown is for Nickel II phosphate.
What the charge for Nickel atom?
Nickel has an atomic number of 28- so if there aare only 26 electrons - 2 are missing and the ion will have a harge of 2+.
What is the formula for a base using the nickel II ion?
Ni2+
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 role of ion pair reagent in mobile phase of HPLC?
The reagent couples with the analyt, making the analyt polar. Now, the reagent-analyt complex can interact with the polar column.
What batteries are used in electric cars?
Nickel Metal Hydride or Lithium Ion batteries are the most widely used.
When nickel combines with fluorine to form nickel fluoride the charge of the nickel ion is what?
The answer is Ni3+

List three types of batteries that might be used on notebooks?
NI-Cad (nickel-cadmium), NiMH (nickel-metal-hydride), and Lithium Ion
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+).
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.
What is the chemical responsible for the mayer's reagent?
the mercury atom will dissociate from the chloride ion
