At 25 degrees C, 0.212 g of barium hydroxide Ba(OH)2 is dissolved completely in sufficient water to make 0.25 litre final solution. What is the hydroxide ion concentration (in mol per litre) in this solution? Give the answer in scientific notation to an appropriate number of significant figures, and state the assumption you must make in order to carry out the calculation.© BrainMass Inc. brainmass.com March 4, 2021, 5:57 pm ad1c9bdddf
<br>Here is some pointers you want to think about if you want to try to solve this by yourself:
<br>To find the concentration we need to know two things:
<br>1. How many moles of OH-1 are present in the final solution
<br>2. How many liters of water are required in order to dissolve completely BaOH2.
<br>Part 2 is essential, since we need to know if to get to 0.25L of solution we need to ...
