ChemLab 32: Preparation for solutions with pH from 1 to 13

Standard Acidic Solutions:

• Mix 2.1 cm³ of 12 M HCl with 248 cm³ of distilled water to make a 0.1 M HCl solution with a pH of 1.
   
• Add 5 cm³ of the 0.1 M HCl to 45 cm³ of distilled water to make a solution with a pH of 2.
   
• Repeat using 5 cm³ of each previously diluted HCl solution and 45 cm³ of distilled water to make solutions with pH 3-6.

 

Standard Neutral Solution:

• Boiled distilled water will have a pH of 7.

 

Standard Basic Solutions:

• Add 1.05 g of NaOH to 249 cm³ of distilled water to make a 0.1 M NaOH solution with a pH of 13.
   
• Add 5 cm³ of the 0.1 M NaOH to 45 cm³ of distilled water to make a solution with a pH of 12.
   
• Repeat using 5 cm³ of each previously diluted NaOH solution and 45 cm³ of distilled water to make solutions with pH 11-8.
