1. The problem statement, all variables and given/known data A saturated solution of SrSO4 has a [SO42-] of 1.0x10-4M. What is the [Sr2+]? A. 3.4x10-3M B. 5.8x10-4M C. 1.0x10-4M D. 3.4x10-7M 2. Relevant equations 3. The attempt at a solution It's a multiple choice practice test and the answer key tells me that A is the answer. When I look at the question, the strontium and sulphate have a 1:1 molar ratio so wouldn't the answer be C? Is this a mistake or am I missing something?
