You're thinking of Lithium metal, which reacts with water to PRODUCE Lithium Hydroxide, which is soluble. This reaction also produces hydrogen gas, which can ignite if the reaction is sufficiently exothermic.  All elements in that group react with water (Lithium, Sodium, Potassium, etc.), increasingly energetically as you move down the column.
Lithium Hydroxide reacts with Carbon Dioxide to produce Lithium Carbonate and water.

Doesn't lithium hydroxide burst into flames when it comes into contact with water?Thanks,Scott Waters

We'll be looking into Lithium Hydroxide for emergency use in P-VI as it is longer lasting per unit of volume, more efficient, and more temperature tolerant. It is also expensive by comparison. However, the sheer volume of material will be smaller, so easier to store.

Thanks Cliff. I was also running the numbers on Pisces VI. We will have the following for 1 pilot and 3 observers for a 8 hour mission time and 5 day emergency use
*400 cuft O2 outside hull emergency use (five 80cuft tanks)
*160-81 cuft O2 inside hull for up to 8hr mission use (two 80cuft bottles allowing for full discharge)
*144 lbs sodasorb emergency use (three 48lb jugs)
*12 lbs sodasorb for up to 8hr mission use (two scrubbers loaded)

Thank you,
