infrared and raman spectra of magnesium ammonium phosphate hexahydrate ( struvite ) and its isomorphous analogues . i . spectra of protiated and partially deuterated magnesium potassium phosphate hexahydrate

Answers

Answer 1

Magnesium potassium phosphate hexahydrate and a number of its deuterated counterparts were studied for their Fourier transform infrared and Raman spectra. By contrasting the spectra obtained at the boiling point of liquid nitrogen with those obtained at ambient temperature and by examining the spectra of a succession of partially deuterated MgKPO4

What is Infrared and raman spectroscopy ?

Raman and infrared spectroscopy both investigate how radiation interacts with molecular vibrations, but they do so in different ways depending on how the photon energy is delivered to the molecule by altering its vibrational state.

While IR spectroscopy depends on a change in the dipole moment, Raman spectroscopy depends on a change in the polarizability of a molecule. In contrast to IR spectroscopy, which measures the absolute frequencies at which a sample absorbs light, Raman spectroscopy measures the relative frequencies at which a sample scatters light.

electrical double layer design for proton-coupled electron transfer electrode processes: recent advances in well-defined electrode−electrolyte interface

Answers

The article aims to highlight the most recent improvements in the PCET procedures for electrocatalysis at clearly characterized electrodeelectrolyte interfaces.

Aim : Here, we focus on the most recent developments in the PCET methods for electrocatalysis at clearly defined electrodeelectrolyte interfaces.

Method: Since the groundbreaking and ongoing studies made by Frumkin and his colleagues initiated in the 1930s, non-covalent interaction, which is controlled by the cation/anion features, is known to play a crucial role in the interfacial water and adsorbate environments correlated to electrodeelectrolyte catalytic properties.

The microscopic perspective of this interaction is still a significant scientific mystery, nevertheless. Recent research based on the well-defined surface and solid-liquid interfacial structure of single-crystal model electrodes revealed novel characteristics of the cation effect.

Practical usage: Designing high-performance electrode and electrolyte materials requires an understanding of the roles played by the electrical double layer (EDL) structure in proton-coupled electron transfer (PCET) electrode processes.

Neon and sodium differ by 1 proton (Neon has 10, Sodium 11) but they react VERY differently. Why does this small change cause such a big effect?

Answers

The reason why this small change between Neon and sodium cause a very big effect is simply because neon is a noble gas with an octet structure in its electronic configuration while sodium is an alkali metal which is univalent electropositive element.

However, despite the fact that these two different elements has a difference of one electron in their outermost shell, yet they individually carry and posses very powerful electronic structure due to their position in the periodic table which makes them react differently

Sodium belong to group 1 of the periodic table while Neon belong to group 0 or the 8th groupSodium has a valence electron of just 1 electron while Neon has a valence electron of 8 electrons Sodium is an alkali metal while Neon is a noble gas

Solution a has a hydrogen ion concentration of 3. 2 x 10-9 and solution b has a hydrogen ion concentration of 6. 9 x 10-5. Which solution is more basic?.

Answers

Solution a is more basic.

Basic solutions are those solutions whose pH is greater than 7.

The pH of a solution is calculated or determined by the hydrogen ion concentration of the solution. The relation between pH of a solution and the hydrogen ion concentration in it is given by :

pH = -log[ H+]

From this relation we can conclude that if the hydrogen ions concentration in a solution is more , the value of pH will become lower.

For Solution a, the pH is given by :

pH(a) = -log [ 3.2 x 10^-9 ] = 8.4948 ≅ 8.5

For Solution b, the pH is given by :

pH(b) = -log [ 9 x 10^-5 ] = 4.04 ≅ 4

Since the pH of solution b is lower than the pH of solution a , solution a is more basic than solution b. Moreover, the pH of solution a is approximately 8.5 which makes it a moderately strong basic solution.

The solubility product is 4n³.

The equilibrium constant for a solid's dissolving into an aqueous solution is called the solubility product constant. It is represented as K(sp).

A solution is said to be saturated when it has dissolved all of the solutes it can. At a certain temperature, no additional solute can dissolve in a saturated solution.

Consider the equilibrium for a saturated PbCl₂ aqueous solution.

PbCl₂(s) ⇄⇄ Pb₂ (aq) + 2Cl⁻ (aq)

The equilibrium constant for the dissociation reaction of the PbCl₂ solution is:

K(sp) = [Pb²⁺] [Cl⁻]²

Now, [Pb²⁺] = n mol/L

In the solution, there is one-mole Pb²⁺ and two moles of Cl⁻ .

Therefore,

[Cl⁻] = 2n mol/L

So, the equilibrium constant for the dissociation reaction will be:

K(sp) = [Pb²⁺] [Cl⁻]²

K(sp) = n × (2n)²

K(sp) = n × 2n × 2n

To know the mass of eaten gummy bears, the following rule of three applies: if 1 gummy bear weighs 3 g, 40 gummy bears weigh how much mass?
