Answer :
A buffer solution contains 0.447 m nahso3 and 0.280 m k2so3. if 0.0367 moles of potassium hydroxide are added to 225 ml of this buffer, basic is the ph of the resulting solution i.e. 10 approx.
The buffer solution, a water-based solvent solution, is created by combining a weak acid and its conjugate base, or a weak base and its conjugate acid. They can be diluted or have small amounts of acid or alkali added to them without the pH of the solution altering. The pH of buffer solutions scarcely changes when a modest amount of a strong acid or strong base is introduced. They are consequently used to keep the pH level constant. The concentration of hydrogen ions in the buffer solution only slightly changes when a little amount of acid or base is diluted or added (pH). Buffer solutions are used in the processes of fermentation, food preservation, medicine delivery, electroplating, and printing because particular hydrogen ion concentrations are necessary for enzyme activity and the blood's ability to carry oxygen (pH). Buffer solutions, which are combinations of a weak acid and its conjugate base or a weak base and its conjugate acid, can be used to maintain pH.
