The buffer solution is the type of solution that contains a weak acid and its conjugate base. In the solution, the concentration of hydrogen ion can be measured by the pH whereas, the concentration of hydroxide can be mea...
What is the relation between pH and pKa? What is the name of the base that has the formula Ba(OH)2? What is the chemical formula for the base cesium hydroxide? When an acid reacts with a base, what compounds are formed? What is ionization energy?
Hydrochloric acid (HCl) is a strong Brønsted–Lowry acid, whereas sodium hydroxide (NaOH) is a strong Brønsted–Lowry base. Mathematically, pKa is defined as the negative logarithm of the acid dissociation constant, Ka. Before going further, let’s have a quick refresher on Ka. A Refresh...
This is used to calculate pKa, the logarithmic constant: PKA = – log10 Ka The larger the pKa value, the smaller the dissociation of the acid and the weaker the acid. Strong acids have a pKa of less than -2. We’ve created this content for informational purposes only, and it reflects...
The pKa of ethanethiol shows it's a weak acid. 8 Thiolate Formed in basic conditions. Sodium thiolate is formed when sodium hydroxide reacts with thiols. 9 Thiol Found in biological systems. Thiols are important in forming disulfide bonds in proteins. 7 Thiolate Active in enzyme catalysis. Thi...

(Acetic Acid: pKa = 4.74) What is the pH of the buffer prepared by adding 20 mL of 0.20 M sodium hydroxide to 50 mL of 0.10 acetic acid? (pKa of acetic acid = 4.76) A buffer solution is prepared by adding 15.00 g of s...
What is the concentration of {eq}X^{2-} {/eq} in a 0.150 M solution of the diprotic acid {eq}H_2X {/eq}?Molarity:Molarity is a concentration unit of moles of solute per liter of solution, meaning the moles of a sample are simply the product of the molar conc...
As a very weak base with a pKa of 8.2, benzotriazole exhibits more acidity than indazole, benzimidazole, and 1,2,3-triazoles. Its stability is enhanced by the fused benzene ring, which contributes to the stability of the conjugate base. ...
Which scenario is correct Scenario 1 Ph/ pKa: 6.401 i will have it will have (0 amount of) Na3C6H5O7, and (100%) Na2C6H6O7 as the sodium will disassociate, at pH /pKa 4.76, there is (Zero amount of) Na2C6HO7 and (100%) NaC6H5O7 and at A Ph/pKa of 3.138 (Zero amount...
