System Cu2 - (2.5 mmol/L CuCl2 / dist. water),
System M - (2.5 mmol/L Disodium Malonate / dist. water),
System (Cu2+M) - (2.5 mmol/L CuCl2 + 2.5 mmol/L Disodium Malonate / dist. water),
System Cu2: The forming of Cu(OH)2 between pH 6.2 and pH 11.6 could be shown.
System M: The forming of malonic acid between pH 6.6 and pH 2.0 could be shown.
System (Cu2+M): At pH 2.0 to 12.0 a malonic acid-copper-complex is formed.
