Which is more dilute solution?
Which is more dilute solution?
The main difference between the dilute solution and concentrated solution is that dilute solution contains less solute and the concentrated solution contains more solute. A liquid with a high solute concentration is called a concentrated solution. A liquid with a less solute concentration is called a dilute solution.
What is Neutralisation curve?
A plot of pH against the volume of alkali added (mL) is known as a neutralization or titration curve (Fig. The significant feature of the curve is the very sharp and sudden change in pH near to the equivalence point of the titration. For a strong acid and alkali this will occur at pH 7.
Why is the equivalence point higher than 7?
At the equivalence point, all of the weak acid is neutralized and converted to its conjugate base (the number of moles of H+ = added number of moles of OH–). However, the pH at the equivalence point does not equal 7. This is due to the production of conjugate base during the titration.
Why is the third equivalence point not observed?
The base used in the titration would have to exceed this value by about 2 pH units to produce the third equivalence point. NaOH at titration concentrations (0.1M – 0.5M) has a maximum pH of about 13 and therefore the third equivalence point is not shown.
How do you know when the equivalence point has been reached?
In both cases, the equivalence point is reached when the moles of acid and base are equal and the pH is 7. This also corresponds to the color change of the indicator. Figure 2. A titration curve shows the pH changes that occur during the titration of an acid with a base.
What is a Ka value?
The acid dissociation constant (Ka) is used to distinguish strong acids from weak acids. Strong acids have exceptionally high Ka values. The Ka value is found by looking at the equilibrium constant for the dissociation of the acid. The higher the Ka, the more the acid dissociates.
What is KA equal to?
Dissociation Constant for Acetic Acid Since x = [H3O+] and you know the pH of the solution, you can write x = 10-2.4. It is now possible to find a numerical value for Ka. Ka = (10-2.4)2 /(0.9 – 10-2.4) = 1.8 x 10-5.

Is Ka a valid Scrabble word?
Yes, ka is in the scrabble dictionary.
What does kindergarten full mean?
Full-day kindergarten is defined as any program lasting more than four hours, not including recess time.
What is a high Ka value?
A large Ka value indicates a strong acid because it means the acid is largely dissociated into its ions. A large Ka value also means the formation of products in the reaction is favored. A small Ka value means little of the acid dissociates, so you have a weak acid. The smaller the value of pKa, the stronger the acid.
Does higher pKa mean stronger acid?
The pKa essentially tells you how much of the acid will actually dissociate. If the pKa is low, then more of the acid will dissociate, representative of a stronger acid.
