Which of the folowing statements is corect conceming the formula of a hydrate experiment? Sinx O All hydrated salts can be converted into anhydrous salts by heating 00 O Heating the hydrated salt too strongly at the beginning, will lead to a decrease in the calculated value of "x. If the dehydration of the hydrate is incomplete, the calculated value of x will be lower than the actual value. O If the mass of hydrated salt and H20 are 0.59 g and 0.24 g, respectively, then the mass % of water of crystallization is 29 % O If1.1g of alum is recorded instead of 1.0 g, the calculated value of "X" will be lower than the actual value.
