Thank you for the quick response!
I'm asking this question not for anything school related, I just have a huge interest in chemistry
The reaction is : CaCO₃(s) + 2HCl(aq) → CaCl₂(aq) + CO₂(g) + H₂O(l).
The Carbonate is divalent and yes, I have googled this, but the reason I'm asking this question is that I cannot figure out how to calculate the volume of 30% HCl needed...
Say the density of a 30% HCl is 1.15 g/ml
I know how to calculate the mass of HCl needed, but how do you factor in that the HCl is in a solution of x amount of water? Am I overthinking?
