Answer #1

Alkaline buffer is formed when a solution contains a weak base and it's conjugate acid. In this type of buffer on adding strong acid, weak base will conlnvert into its conjugate acid by accepting H+ or by donating OH-.

So answers are

Option 1st : the weak base of alkaline buffer will accept hydrogen protons when a strong acid is added to the solution

And option 2nd : an alkaline buffer is a mixture of weak base and it's conjugate acid.

And option 6th : the conjugate acid of an alkaline buffer will donate hydrogen protons when a strong base is added to the solution.

Most biological systems must maintain a very narrow range of pH; therefore, buffers allow the biological solution to function correctly. Blood is a good example of a biological system that must maintain a pH in a very narrow range from 7.3 to...

    Lab 5 Buffers 1. Dissolved ions in salt solutions can act as acids or bases and react with water to produce hydronium ions or hydroxide ions that contribute to the pH of the salt solution. Since strong acids and strong bases completely ionize in solution, the reverse reaction essentially does not occur, meaning that the resulting conjugate base of a strong acid or conjugate acid of a strong base do NOT act as acids or bases. Ions that are conjugate...

    The weak acid of the buffer system is used to prepare the buffer by reacting with a strong base. The conjugated base is going to be obtained from some of the weak acid in reaction with NaOH 1M. This means you need to calculate the total amount of weak acid needed and the amount of 1.00 M NaOH solution you will have to add to create its conjugate form in solution.   Use 1.0M of each of these acids and basic...

    A buffer solution is able to maintain a constant pH when small amounts of acid or base are added to the buffer. Consider what happens when 1 mL of a 5 M solution is added or 0.005 mol of HCl are added to a 100.0 mL solution acetic acid buffer that contains 0.0100 mol of Acetic acid, HC,H,O,, and 0.0100 mol of sodium acetate, NaC,H,O,. The initial concentration of both the acid and the base are 0.0100 mol/ 0.1000 L...
