In a weak acid when [HA]=[A-]the pH = the pKa. What is the pH after adding 0.50 moles HCl to a solution of HA =1 mole and A- = 1 mole. The pKa of the weak acid = 4
Assuming that an acid (AH) which has pKa=5.7 is added to the buffered solution with pH=6.8. Calculate percentage of non-ionized acid (AH) that will appear in the solution once the equilibrium is reached. Answer is numerical. Round the answer to the nearest whole number. Don't write % simbol in the answer.
A solution of a weak acid acid has three times as many conjugate acid molecules as conjugate base molecules. If the pKa of lactic acid is 3.85, what is the pH of such a solution?
1)Which expression is the correct form of the Henderson-Hasselbalch equation? pH = pKa + log([base]/[acid]) pKa = pH + log([base]/[acid]) pH = pKa − log([base]/[acid]) pH = pKa + log([acid]/[base]) 2) Use the Henderson-Hasselbalch equation to calculate the pH of a buffer solution prepared by mixing equal volumes of 0.220 M NaHCO3 and 9.00×10−2 M Na2CO3. (Ka values are given in Appendix C.) Express your answer using three significant figures.

I need to know the % output when :
weak acid( pKa=6) is in pH of urine at 6 and pH or urine at
8.
Also the weak base (pKa 7) in pH of urine at 6 and pH or urine
at 8.
Effect of urine pH on delivery route: Weak organic acids and bases can reach the luminal fluid (the filtrate, the primary urine) either by glomerular filtration in Bowman's capsule or by secretion in the proximal tubule. In...
When the concentrations of weak acid [HA] and its conjugate base [A-] are equal, what is the relationship between the pH and pKa based on the Henderson-Hasselback equation? pH < pKa pH = pKa pH > pKa
