For a buffer solution, pKa Equals the solution's pH. Choose a molecule with a pKa close to 2.0, such as sodium bisulfate, in order to prepare pH = 2.0.
In order to create a buffer solution, a weak acid and salt, such as CH3COOH and CH3COONa, or a weak base, such as NH4OH and NH4Cl, are typically combined with salt. To understand how a buffer works, think about the example of a solution created by combining sodium acetate with acetic acid. Is called as buffer solution.
The sodium bisulfate salt of the anion has the chemical formula NaHSO4 and is often referred to as sodium bisulfate. An equivalent of sodium base, known as sodium bisulfate, is used to partially neutralize sulfuric acid.

The Answer is the Mendeleev left several blanks in the periodic table for the elements that had yet to be discovered.
Periodic table is an arrangement of chemical elements in a table made up of rows and columns, rows are called periods and columns are known as groups.
In 1869, Dimitri Mendeleev who was a Russian Chemist published first organized periodic table.
Answer:
Acids
Explanation:
Acids have a low PH, so they release H+ ions in water. Bases release OH- ions and have a high PH
Answer:
9x+y+8
Explanation:
We know this because you add 3x and 6x to get 9x
then we only have one y so put y by itself then subtract 15 and y which gets us 8
