I am mostly interested in the reaction by-products as these materials may be used in food grade polymers. Thank you Logged billnotgatez Global Moderator Sr. Member Posts: 4431 Mole Snacks: +224/-62 Gender: Re: Calcium carbonate reactions with acid ...
The salt anion appeared to have little or no effect on the rate of reaction. At a 1:1 mole ratio of acid to carbonate, the reaction was zero-order to about 95% reaction. With tetraethyl-ammonium hydroxide catalyst at 0.4 mol% (based on carbonate moles), the activation energy was 20.8 ...

Hydrochloric acid(HCl) is commonly used acid for carbonate acidizing treatments, due to its low cost and fast reaction withcarbonate rocktypes (limestone and dolomite). It is mostly used with the concentration of 15% (by weight) solution, to provide enough dissolving power of acid and limit th...
