Calcium Bromide (Anhydrous) Not Dissolving?

  1. Oct 8, 2013 #1
    Hi All,

    So, I am having trouble with a solution I am trying to prepare in the lab which baffles me and here it is:

    --Water used is DI Millipore Grade Water--

    I have Calcium Bromide (Anhydrous) %99.5 from Alfa-Aesar, CaBr(2) is supposed to be highly soluble about 125g/100ml at 0 Degrees Celsius. I am just trying to make a 0.1M solution approximately 20g/L, yet I cannot???

    What I see is a suspension like solution of whitish particulates (and even a couple of thread like objects), no matter how much I stir/heat the solution.

    Any Insights???

    Thank You.

    Working on the basics here.

    What is the received date on the CaBr2?

    Is the power smooth or clumpy?
