Lower values of ka correspond to
WebSep 5, 2024 · Therefore, a larger Ka corresponds to a lesser pH value. How do you compare Ka values? The greater the Ka value for an acid is relative to the strength of the acid, or the magnitude at which it will disassociate in water. The closer the Ka value is to one the stronger it is (the term “strong acid” means that it completely disassociates). WebThe K values give us an idea of the relative amounts of products and reactants at equilibrium. If K is large, there is a large amount of H⁺ or OH⁻ at equilibrium and very little undissociated acid or base.

WebJan 8, 2024 · or a more simplified way to show this formula: Ka= [products]/ [reactant] The larger the Ka the stronger the acid, generally if it's above 1 it's a stronger acid, less than 1 it's a weaker acid. The larger the Ka value the smaller the pKa value so it is an inverse relationship. Top Uma Patil 2A Posts: 99 Joined: Fri Sep 24, 2024 12:16 pm

Then we’ll find the pKa values for those. We know that acid loses the proton in an acid-base reaction, so obviously the acetylene species on the left is our acid. And since the NH 2– accepted that proton, NH 3 is the conjugate acid.

Answer link enemy infantry division symbolWebpKa is the negative log of the equilibrium constant Ka, so -log (Ka). So you'd need to calculate the Ka and you can do that by measuring the concentrations of your reactants and products at equilibrium and plug them into the equilibrium expression for the deprotonation of water.
