making cesium-gluconate solution

[Dennis Churchill]

I need advice on making a 140 mM cesium-gluconate solution. The best I figure is to make a 140 
mM CsOH solution and then titrate it to pH7.0 with gluconate. I tried this and am not satisfied. 
The pH bounced around 7.0 and never really settled down. There must be a way to calculate 
this. Any recommendations?

Thanks
