What is the pKa of water (H2O)?
The pKa of water (H2O) is approximately 15.7.
What is the pKa of distilled water?
About 15.74, so you need a fairly strong base to deprotonate it.
What is the relationship between the pKa value and the ionization of water molecules?
The pKa value is a measure of the strength of an acid. In the case of water, which can act as both an acid and a base, the pKa value indicates the extent to which water molecules ionize into H and OH- ions. A lower pKa value means that water molecules are more likely to ionize, while a higher pKa value means they are less likely to ionize.
What is the pKa of water and how does it affect its chemical properties?
The pKa of water is about 15.7. This means that water is a weak acid. Its pKa value affects its ability to donate or accept protons, which influences its chemical properties such as its ability to act as a solvent and participate in chemical reactions.
PKa value of diethylmalonate?
The pKa value of diethylmalonate is around 13.1. This makes diethylmalonate a weak acid, as it tends to not completely dissociate in water.
Does pka changes with temperature?
pKa (dissociation constant) is variable with temperature.

At a certain temperature a 0.25 M solution of HF has a pH of 2.3 What is the Ka of HF at this temperature?
To find the Ka of HF at this temperature, you can use the formula pH = pKa + log([A-]/[HA]). Since HF is a weak acid, [A-] is equal to [H+], so you can substitute [H+] for [A-] in the formula. Rearrange the formula to solve for pKa. Then convert pKa to Ka using the relationship: Ka = 10^(-pKa).
What is the pKa value of water and how does it impact its chemical properties?
The pKa value of water is approximately 15.7. This value indicates that water is a weak acid. The pKa value of water impacts its chemical properties by determining its ability to donate or accept protons in chemical reactions. This property influences the pH of water and its role as a solvent in various biochemical processes.
What is the pka of nh3?
The pKa of NH3, also known as ammonia, is approximately 38. Ammonia is a weak base, meaning it does not completely dissociate in water to form hydroxide ions. The pKa value indicates the extent to which ammonia will accept a proton in a chemical reaction. A higher pKa value signifies a weaker acid or base.
Is it true that the sum of pka and pkb is always equal to 14 at all temperature for any acid?
In general, at 25°C the sum of pKa and pKb for a conjugate acid-base pair will equal 14 due to the auto-ionization of water. However, at different temperatures, the sum may vary slightly due to changes in the equilibrium constant of water ionization.
What is the pka value for NaCN?
NaCN doesn't really have a pKa. In water it becomes Na^+ and CN^-. The CN^- is a base so it will have a Kb and pKb. If you want the pKa of the conjugate acid (HCN), you can find that from 1x10^-14/Kb.
What is the pka of cyclohexane?
pKa is measured for acid in aqueous solution while hexane is an organic liquid immiscible with water so pKa value is meaning less for hexane.
