The acid dissociation constant, denoted as Ka, is the equilibrium constant for the dissociation of an acid into its conjugate base and a hydrogen ion. It is defined as [H+][X-]/[HX], where [H+], [X-], and [HX] represent the molar concentrations of the hydrogen ion, the conjugate base, and the undissociated acid, respectively.

Can equilibrium constants be negative?

No. An equilibrium constant is derived from the products, powers, and ratios of the activities (essentially the concentrations) of the species that are in equilibrium. Since there is no such thing as a negative concentration, there is no way their products, powers or ratios can yield a negative number.


What is the term for the process of an ionic compound dissolving in water and separating into positive and negative ions?

The term for this process is "dissociation." In this process, the positive and negative ions of the ionic compound become surrounded by water molecules, allowing them to separate and disperse throughout the solution.


When ionic compounds dissolve in water what do they form?

When ionic compounds dissolve in water, they form ions. The positive and negative ions in the compound separate in the water due to the polar nature of water molecules. This process is known as dissociation.


When NaCl is dissolved in water negative end of the water molecules is attracted towards what?

Ion-dipole attraction dictates that the negative pole of a water molecule will be attracted to the sodium cation and the positive pole of a water molecule will be attracted to the chloride anion.


What piece of information will tell you which way the equilibrium of a reaction will shift due to a change in temperature?

The sign of the enthalpy change (∆H) of the reaction will indicate the direction in which the equilibrium will shift with a change in temperature. If ∆H is negative (exothermic reaction), an increase in temperature will shift the equilibrium towards the reactants; if ∆H is positive (endothermic reaction), an increase in temperature will shift the equilibrium towards the products.

Can ksp be negative?

No, the equilibrium constant (Ksp) cannot be negative. It is always a positive value or zero, representing the extent of solubility of a salt in a solution.

Net exports are negative?

positive net exports increase equilibrium GDP while negative net exports decrease it.


Mountains in china positive and negative effect?

it can be positive because it can protect China from constant invasion but it is also negative because it restricts cultural diffusion.


If a process is carried out at constant pressure P and the volume V of the system decreases then V is negative positive and the work w is negative positive zero?

In this case, V would be negative, and work w would be positive.


Can a negitave number be a constant term?

Yes, it can. Constants can be both positive and negative numbers.


If the constant term in the factoring of a trinomial is positive then the signs in both binomial factors will be negative?

Not necessarily. They could both be positive.


How does supply shock affect equilibrium price and quantity?

Because supply shock is a sudden change of a good. Meaning if it is a negative shock, the equilibrium price and quantity of course will go down. And if it is a positive shock, vice versa of negative.
