What are the hydronium and hydroxide ion concentrations in a solution whose ph is 6.52?

Chemistry

erica [24]1 year ago
3 0

A solution with a pH of 6.52 has a hydronium ion concentration of 3.02x10-7 mol/L and a hydroxide ion concentration of 3.31x10-8 mol/L.

The hydronium ion concentration of a solution can be calculated from pH by using 10^{-pH}. For a pH of 6.52, hydronium ion concentration is 3.02x10-7 mol/L.

The concentration of hydroxide ions can be determined by identifying the value of pOH. The sum of pOH and pH is equal to 14, which is based on the negative logarithm of the ion-product constant of water. At a pH of 6.52, pOH is equal to 7.48.

The relationship between pOH and hydroxide ion concentration is the same as the relationship between pH and hydronium ion concentration. With this, the hydroxide ion concentration at pOH of 7.48 is 10^{-7.48} or 3.31x10-8 mol/L.

Rank the following transitions in a hydrogen atom in order of increasing wavelength of electromagnetic radiation that could prod
Dmitrij [34]

Answer:

n=2 to n=4 < n=6 to n=8 < n=10 to n=12 < n=14 to n=16

Explanation:

According to Neils Bohr, electrons in an atom are found in specified energy levels. Transitions are possible from one energy level to another when the electron receives sufficient energy usually in the form of a photon of electromagnetic radiation of appropriate frequency and wavelength. The energy of this photon corresponds to the energy difference between the two energy levels. Thus the higher the energy difference between energy levels, the greater the energy of the photon required to cause the transition and the shorter the wavelength of the photon.

High energy photons have a very short wavelength. It should be noted that as n increases, the energy of successive energy levels decreases and transitions between them now occurs at longer wavelengths. Hence, the highest energy and shortest wavelength of photons are required for transition involving lower values of n because such electrons are closer to the nucleus and are more tightly bound to it than electrons found at a greater distance from the nucleus.

Hence transition involving electrons at higher energy levels occur at a longer wavelength compared to transition involving electrons closer to the nucleus. This is the basis for the arrangement of wavelengths required to effect the various electronic transitions shown in the answer.

Write a conversion factor that converts between moles of calcium ions in calcium phosphide, Ca3P2, and moles of Ca3P2.
cricket20 [7]

The conversion factor between moles of calcium ion and moles of Ca_3P_2 in  Ca_3P_2 would be 3 to 1.

<h3>Mole fraction</h3>

Ca_3P_2 if formed from 3 carbon atoms and 3 phosphate atoms according to the equation:

3Ca + 2P --- > Ca_3P_2

Thus, there are 3 moles of calcium in every 1 mole of  Ca_3P_2.

The conversion factor between moles of calcium and moles of  Ca_3P_2 will. therefore, be 3 to 1 or simply 3:1.
