Help please!! I don't need the work shown, but if you can explain how I'm supposed to set up problems like these, that would be great! I understand how to calculate it once its set up, but I don't know how to get there from this

If you want to create an electrical current, which situation would produce a solution capable of this

When balancing a chemical equation:

For each of the following compounds, decide whether the compound's solubility in aqueous solution changes with ph. if the solubility does change, pick the ph at which you'd expect the highest solubility. you'll find ksp data in the aleks data tab. compounds does solubility change with ph
