The latent heat of crystallisation of sodium chlorate

AI Thread Summary
The discussion centers on the use of a saturated sodium chlorate solution as a thermal storage medium for heating water in a house or boat using solar energy. Key concerns include the heat capacity of sodium chlorate crystals, as there is uncertainty about the amount of heat generated per gram. Additionally, there are questions regarding the corrosive nature of the solution and its potential effects on storage containers, particularly whether a stainless steel vacuum-insulated tank would be suitable. The participant acknowledges the need for further research to understand the engineering implications of using sodium chlorate in this context.

I am a retired electronic engineer and no scientist. I am considering the use of a saturated solution of sodium chlorate as a thermal store. My problems are: 1/ I have no idea of the quantities involved in terms of heat/gram of crystals. My intention is to maintain a supply of hot water for a house or boat using solar heating. 2/ I don't know of any corrosive effects of such a solution on the container. Would a stainless steel vacuum-insulated tank work?

I suspect it would be rather corrosive though.
Thanks, it seems to have at least one of the answers. It is way out of my comfort zone so I will have to study it for engineering rather than academic truths. Thanks again.
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...

Thread 'Resists for etching Aluminium with NaOH'

I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
