[H+] = 10 raised to the -pH, or 10 raised to -3, which equals .001. Then Ka = [H+] squared / Molarity of the solution, which equals 1.72 E(-6).
I Think it's H3PO4 + H2O yields H3O+ + H2PO4-
First because the later ones are trying to take more H plus ions from an already negative ion, which is harder.
Helium has the highest first ionization energy and francium has the lowest first ionization energy.
No. Nonmetals have a high first ionization energy.
Sodium's first ionization energy is 495 kJ / mol.
The first ionization energy of plutonium is 584,7 kJ/mol.
Atomic radius is inversely proportional to first ionization energy. As atomic radius increases, first ionization energy decreases.
The first ionization energy of francium is estimated to be 380 kJ/mol.
The lowest first ionization energy is for caesium: 375,7 kJ/mol.
Helium has the highest ionization energy.
Nitrogen has the highest first Ionization potential.
The first ionization energy is 1681 kJ/mol.
The alkali earth metals have the smallest first ionization energies.
Ne (Highest First Ionization Energy) C Be Mg Sr (Lowest First Ionization Energy)
The first ionization energy for carbon is 1 086,5 kJ/mol. The first ionization energy for oxygen is 1 319,9 kJ/mol.
In a group the first ionization energy decrease going down.In a period the first ionization energy increase from left to right.
Second ionization coefficient is NOT higher than the first ionization coefficient. Matter a fact, when compared to the first it could be neglected, but the number of electrons captured from cathode surface by positive ions can not be neglected, there lays its significance.
Helium (He) has the highest first ionization energy. Ionization energy increase as you go across the periodic table from left to right
The ionization energy (first) of einsteinium is 619 kJ/mol.
The first ionization energy of nitrogen is 1402.3 kJ/mol.
The first magnesium ionization energy is 737,7 kJ/mol.
The first ionization energy of oxygen is 1313,9 kJ/mol.
The First Ionization Energy generally decreases.
The first ionization of aluminum is Al(g) -> Al+(g) + e-
Calcium has a higher first ionization energy than potassium.
