The percent of AlBr3 is grams per 100 grams of solution. You need to make an assumption that this low concentration (0.0330%) will yield a solution with a density of approximately 1.00 g/mL. (so 0.00330 g AlBr3/100g solution = 0.0330 g AlBr3/100 mL)
Since the concentration is given with a specific number of significant digits, use the same number of significant digits in your answer.
Benzoate said:don't you mean 0.00330 g AlBr3/100g solution = 0.00330 g/100 mL AlBr3 not 0.00330 g AlBr3/100g solution = 0.0330/100 mL g AlBr3
Benzoate said:Anywh, would you now multily (.00330 g AlBr3/100 g AlBr3)*(1 mol AlBr3 /266.68 g AlBr3)*(3 mol Br1-/1 mol AlBr3) to get the number of moles of Br1- ions? If I followed the correct procedure, would divide my number of bromine moles by 10^6 g to calculate the concentration?
A concentration ion problem is a type of problem that involves calculating the concentration of ions in a solution. It typically involves using the molar concentration of a compound and its dissociation constant to determine the concentration of each individual ion in the solution.
To solve a concentration ion problem, you will need to first identify the compound and its dissociation constant. Then, you will need to use the molar concentration and dissociation constant to set up an equation, which can be solved using algebraic methods. Finally, you can use the solution to calculate the concentration of each individual ion in the solution.
Some common mistakes made when solving concentration ion problems include using incorrect values for the dissociation constant or molar concentration, not considering the charge of the ions when setting up the equation, and not properly accounting for the stoichiometry of the reaction. It is important to double check all values and calculations to avoid these errors.
Temperature and pressure can affect concentration ion problems by altering the dissociation constant of the compound, which can then impact the concentration of each individual ion in the solution. It is important to use the correct dissociation constant for the given temperature and pressure to ensure accurate calculations.
Concentration ion problems have many real-world applications, including in environmental science, pharmaceuticals, and water treatment. They can be used to determine the concentration of pollutants in water, calculate the correct dosage of medication, and ensure safe and effective water treatment processes.
