Raman and IR spectra show a strong increase in intensity of the N–H stretching bands as well as narrowing of the bands related to the NH4+ ions upon cooling. These changes indicate that the phase transition is due to orientational ordering of the NH4+ ions. Analysis of the Raman data ...
Classify the following as a strong or weak acid and/or base: HSO_4 ^- Which one of the following pairs of acids is incorrectly listed? The stronger acid is first and the weaker acid is second. A. HClO; HClO2 B. HNO3; HNO2 C. H2SO4; H2SO3 D. H2SO3...
Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Ammonium fluorosilicate reacts with water to form hydrofluoric acid, a source of fluoride ions. Unlike other halide ions, the fluoride ion is highly reactive, acting as a weak base and participating in some ...
nitrogen fertilizerammonium sulfate, also known as ammonium sulfate, is the earliest production and use of a nitrogen fertilizer at home and abroad. It is usually used as a standard nitrogen fertilizer, nitrogen content between 20% to 30%. Ammonium sulfate is a strong acid and weak base salt,...
strong acid b. strong base c. weak acid d. weak base e. conjugate acid f. conjugate base In the following reaction, identify the weak acid and weak base and then give the conjugate acid and conjugate base. H2O(l) + HCO2H(aq) arrow In the following...
The strength of hydrogen bond appears to be modified at the phase transition: in the low-pressure phase NH 4N 3 behaves as system with very strong hydrogen bonding whereas changes of spectra with pressure in the high-pressure phase are indicative of weak or medium-strength hydrogen bonds. The...
In this reaction, NH4HS reacts with water to produce NH4OH and H2S. NH4OH is a weak base, while H2S is a weak acid. Therefore, the subsequent reaction with a strong base, such as NaOH or KOH, would follow the neutralization reactions discussed earlier. ...
site N(CH3)462. When the effective size of A site is relatively large, it behaves like an inorganic ion. In this case, the effect of hydrogen bonds, between molecules and the surrounding inorganic cage, is relatively weak comparing with the dominating size effect of molecules and ions. ...
If the acid is weak, indicate the value that (H3O+) is less than. Which base has the lowest pKa? a) CH3NH2 b) C2H5NH2 c) C6H5NH2 d) NH3 Hydrochloric acid (HCl) has a pK_a = -3. Is it a strong acid or a weak acid? Why? What is the...
(Figure S1, S refers to figures and tables in theSupporting Information) shows that both reflection position and intensity agree very well. A few weak reflections could neither be assigned to (NH4)H2(PO2NH)3, nor any other known compound; they indicate a small proportion of an additional ...
