Mark asked: 'just to check, is there such thing as CaClOH ?'
My reply: Yes!!!! But not in your syllabus.
In the reaction of HCl and limestone under furnace and boiler conditions, CaClOH is an INTERMEDIATE product.
'intermediate product' means, the reaction produce this product and this product (known as intermediate product) will further react or continue in the reaction to form the final product.
If not, under NORMAL conditions, HCl will react with CaCO3 ( limestone) to form carbon dioxide, calcium chloride and water.
