What is the formula for rubidium nitride?
Rubidium Nitride Rb3N Molecular Weight — EndMemo.
Is ammonium acetate ionic or molecular?
Its molecular formula is C2H7NO2 and its molar mass is 77.08 g mol–1. Ammonium acetate is the salt of acetate ion COO–1 (from acetic acid dissociation in water) and ammonium ion NH4+ (from ammonia dissociation in water).
Is nh4ch3co2 an acid or base?
Ammonium acetate is a chemical compound with the formula CH3COONH4 (or C2H4O2. NH3 or C2H7NO2). It is a white solid, which can be derived from the reaction of ammonia and acetic acid. As the salt of a weak acid and a weak base, ammonium acetate has a number of distinctive properties.
Is ammonium acetate soluble in water?
Similarly, is rbno3 soluble or insoluble?
Rubidium nitrate is a white crystalline powder that is highly soluble in water and very slightly soluble in acetone. In a flame test, RbNO3 gives a mauve/light purple colour.
Is ammonium acetate an acid or base?
Ammonium is a weak acid, and acetate is a weak base. It is a quirk of nature that the acidity of NH4 + (pKa 9.25) exactly balances the basicity of acetate (pKb 9.25), such that dissolution of ammonium acetate salt in pure water produces a neutral pH solution [87, 88].
Is rbso4 soluble?
Rubidium Sulfate is a moderately water and acid soluble Rubidium source for uses compatible with sulfates. Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble.
Is magnesium phosphate soluble in water?
h) All phosphates are insoluble except those of sodium, potassium and ammonium. Some hydrogen phosphates, such as Ca(H2PO4)2, are soluble. I) All sulfides are insoluble except those of ammonium, sodium, calcium, potassium, magnesium, barium and strontium. All of these are slightly hydrolyzed in water.
Is znco3 soluble in water?
Zinc carbonate is soluble in dilute acids, alkalies and in ammonium salt solutions. It is insoluble in water, ammonia, pyridine, alcohol and acetone. Zinc chloride is very soluble in water, and quite soluble in alcohol and acetone. It is also soluble in hydrochloric acid, glycerol and ether.
What is the general rule for the solubility of nitrate salts?
Salts containing nitrate ion (NO3–) are generally soluble. Salts containing Cl –, Br –, or I – are generally soluble. Important exceptions to this rule are halide salts of Ag+, Pb2+, and (Hg2)2+. Thus, AgCl, PbBr2, and Hg2Cl2 are insoluble.
Why is rubidium chloride soluble in water?
Rubidium chloride is used as a gasoline additive to improve its octane number. Rubidium chloride is an excellent non-invasive biomarker. The compound dissolves well in water and can readily be taken up by organisms. Once broken in the body, Rb+ replaces K+ in tissues because they are from the same chemical group.
Are strong bases soluble?
Strong bases like strong acids dissociate 100% in water. As such all the strong bases are ionic compounds where OH– is one of the ions. Such compounds are called hydroxides. Not all hydroxides are strong bases since not all hydroxides are highly soluble.
Besides, is nh4ch3coo soluble or insoluble?
Ammonium acetate (acetate of ammonia) is a colorless crystalline mass consisting of extremely hygroscopic small needle-shaped crystals. At a temperature above 144°C, the reagent undergoes decomposition forming acetamide: NH4CH3COO = CH3CONH2 + H2Ob. It is very soluble in water (58.6% at 4°С), soluble in ethyl alcohol.
Is cs2so4 soluble in water?
Caesium sulfate or cesium sulfate is the inorganic compound and salt with the formula Cs2SO4. It is a white water-soluble solid that is used to prepare dense aqueous solutions for use in isopycnic (or “density-gradient”) centrifugation.
Is rbso4 soluble in water?
As a metal, no. It will react explosively with water, forming rubidium hydroxide and hydrogen gas. Rubidium hydroxide is soluble in water. Rubidium metal reacts violently with water, forming rubidium ions.
What is the name of ch3coonh4?
Is ammonium acetate a precipitate?
Ammonium acetate, also known as spirit of Mindererus in aqueous solution, is a chemical compound with the formula NH4CH3CO2. It is a white, hygroscopic solid and can be derived from the reaction of ammonia and acetic acid. It is available commercially. Ammonium acetate.

Similarly, is agpo4 soluble in water?
Yes, Na2SO4 is soluble in water.
Is MgS soluble in water?
The sulfides of all metals except barium, calcium, magnesium, sodium, potassium, and ammonium are insoluble in water. BaS, CaS, and MgS are sparingly soluble. 7. The hydroxides of sodium, potassium, and ammonium are very soluble in water.
Is nh4c2h3o2 soluble or insoluble?
Ammonium Acetate is a white solid crystal at room temperature, density 1.17 g/cm3, melting point 114 Â°C. It is hygroscopic and soluble in water.
