the equilibrium for the decomposition of sodium peroxoborate can be depicted by the following equation: NaBO3 H2O (aq) -> NaBO2 (aq) + H2O2(aq) use le chatelier's principle to explain why the synthesis of peroxoborate used in this experiment should be successful. lab details: dissoleved 4.75g of borax and 1g of NaOH in 20 mL warm water. cooled mixture in ice bath. prepared a solution by adding 5.75 ml of 30% H2O2 to 15 mL of water and slowly add to borax solution. stir keep cool and wait for crystals to form. add additional H2O2 if crystals cannot be seen past 15 minutes. use vacuum filtration
