• What is the difference between distilled water, double distilled water, deionized water, demineralised water, mineral water normal water
• How many molecules are in 0.001 moles of water?
• How many moles are in 100 water molecules?
• What is a \"standard solution\"? Why standard solutions are prepared?
• If you have a solution that is 5% (w/v) of an alcohol in water, what mass of alcohol is present in 1.0 L of this solution?
•  How do you determine concentration of hydrogen ions at given pH of a solution?
  
• What will be the molarity of hydrogen ions in a pH 5 solution?
• What is the meaning of the equivalence point of a titration curve, for what purposes are titrations used?
• What is a weak acid and a strong base? Explain by 2 examples.•What is the difference between concentration and activity?
• What is complexation and what is a complexation constant?
• What are: Solubility product, colloids, aquo-ion, ion strength, element speciation, and metal speciation?
• Calculate for each experiment the masses needed to produce the respective solutions.
