Dark energy and dark matter seem over analyzed, although they are no different than gravity and wind. Dark energy can be the pulling caused by black holes, stars, and large planets. Dark matter also is just the effect of cosmic dust and debris pushed from explosions but also pulling caused by distant gravitational bodies.
Answer:- The pH of the buffer solution will be 4.04 .
Solution:- Sodium acetate added to acetic acid makes a buffer solution and the pH of buffer solution is easily calculated by using Handerson equation:

We are adding 25.00 mL of each, so the total volume of the buffer solution will be 50.00 mL.
We can calculate the concentration of base which is sodium acetate and acid by using dilution equation:


for base:


Similarly, for acid:


pKa is calculated from given Ka value as:


pKa = 4.74
Let's plug in the values in Handerson equation:

pH = 4.74 - 0.70
pH = 4.04
