BASED ON THIS EXPERIMENT, what is the ion to ion ratio of the product strontium sulfate and what is the chemical formula? STEP BY STEP
Strontium sulfate can be formed from the reaction between strontium nitrate and sodium sutsenu the ion exchange mechanism. strontium nitrate + sodiume sulfate strontium sulfate-sodium nitrate The product strontium sulfate has limited solubility in the reaction media (water) and thereone quantitation of product can be achieved by measurement of product mass. A series of test ratios of 02 M Sr(NO,, and Na:SO. solutions will be prepared and mass of the product formed will be measured T determine the formula of strontium sulfate, we consider the following reaction series: Test mole ratio Strontium Mole of Strontium Sodium Mole of Sulfate Mass of Str Sulfatelml) 12 1.5 2.0 3.0 4 0 4.5 4 8 Sulfate Nitrate fal 4 8 4 5 4 0 ation anion 2.4 x 10E-4 401 3:01 2:01 1:01 2:02 1 03 104 9 6x 20E-4 2 0 1.2 Note Unit, M-malt. e volume of solation-mole/V Molar concentration: = mole of solutExplanation / Answer
A:- The value of a=1, b=1, because the oxidation states of Sr^+2 and SO4^-2
So, the a/b ration = 1/1 => 1:1
Molecular formula for Strancium sulfate is SrSO4,
Balanced reaction:
Sr(NO3)2 + Na2SO4 -------> SrSO4 + 2 NaNO3
