Hydrogen peroxide / sodium or potassium permanganate: reaction type. It coats the CaCO3 which forms a barrier and the reaction between the calcium carbonate and the sulphuric acid cannot proceed. Still have questions? Use MathJax to format equations. This is a nice little question that my chem prof used to ask at times to catch out the "sleepers" in his chemistry class: CaCO3(s) + H2SO4(aq) → CaSO4(s) + H2O(l) + CO2(g). I went to a Thanksgiving dinner with over 100 guests. I agree with the comment explaining that you can't consider it a decomposition reaction as written.

Does history use hypothesis testing using statistical methods? Calcium Carbonate + Sulfuric Acid = Calcium Sulfate + Carbon Dioxide + Water. Calcium chloride, CaCl2 , a soluble ionic compound, and sodium carbonate, Na2CO3 , also a soluble ionic compound, will react to form calcium carbonate, CaCO3 , an insoluble solid that precipitates out of solution, and sodium chloride, another soluble ionic compound. Should I call the police on then? So the reaction equation: CaCO3 + H2SO4 → no reaction : is correct. What's the etiquette for addressing a friend's partner or family in a greeting card? It coats the CaCO3 which forms a barrier and the reaction between the calcium carbonate and the sulphuric acid cannot proceed. What do you think of the answers? therefore no further reaction can take place as calcium carbonate particles can not contact to the acid. Active 3 years, 2 months ago. How to solve a linear problem A x = b in PETSC when matrix A has zero diagonal enteries? Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. ? Geologists use it as their reference point - anything more soluble is "soluble", anything less is insoluble.) To learn more, see our tips on writing great answers. This is explained if you look at the state symbol for CaSO4 - which is a solid. You would see the reaction start, a few bubbles of CO2 come off and then stop as the surface of the CaCO3 becomes "passivated" by the solid calcium sulfate. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. Trevor has gotten to the heart of the problem, but there is a reaction, at least for a short while. What type of reaction is the reaction between an acid and a carbonate? Preparation of sulfuric acid through Contact process. It only takes a minute to sign up. Join Yahoo Answers and get 100 points today. (Also, if you use concentrated H2SO4, the CaSO4 should dissolve. rev 2020.11.24.38066, The best answers are voted up and rise to the top, Chemistry Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us. The calcium sulphate that is formed is not soluble in the acid solution. Get answers by asking now. That is why in the laboratory preparation of CO2 from CaDO3, hydrochloric acid must be used - for example in the Kipp's Apparatus. How can rotamers of alpha-keto esters be named to distinguish between different geometries? (Well, it's slightly soluble. Should live sessions be recorded for students when teaching a math course online? How could I align the statements under a same theorem. Still, it should flake off slowly by the agitation induced by bubbles of CO2 forming - the reaction usually doesn't stop completely. What is chemical decomposition in the context of a crystal or amorphous solid? How does an incomplete reaction occur in steam distillation and what does it have to do with equilibrium. Well, hydrochloric acid is an acid, and calcium carbonate is a base. Reaction: CaO+H2SO4--->H20+CaSO4 When calcium Oxide and Sulphuric acid are combined, Water and Calcium sulphate and Water are formed. Are Van Der Waals Forces the Similar to Van der Waal Equation? You can sign in to give your opinion on the answer. Find the coordinates of a hand drawn curve. MAINTENANCE WARNING: Possible downtime early morning Dec 2/4/9 UTC (8:30PM…, “Question closed” notifications experiment results and graduation. I found that an impervious layer of Calcium sulphate is formed around the marble chips. CaCO3(s) + H2SO4 --> CaSO4(s) + CO2(g) + H2O(g). Examples of back of envelope calculations leading to good intuition? What is the difference between reacting and dissolving? ), calcium carbonate does react with sulfuric acid, THIS IS NOT TRUE ; CaCO3 AND H2SO4 REACTION TAKES PLACE BUT AFTER SOME, TIME CaSO4 IS FORMED THEREFORE THE SURFACE BECOMES PASSIVE, CaCO3 + H2SO4 .........>CaSO4 + CO2 + H2O, (S) (l) (s) (g) (g). This is why it's important to include state symbols in equations. What type of chemical reaction is sulfuric acid with calcium carbonate? site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. I thought it would be a double replacement and also a decomposition reaction because $\ce{H2CO3}$ immediately breaks down to $\ce{H2O}$ and $\ce{CO2}$. The calcium sulphate that is formed is not soluble in the acid solution. You would need to explicitly show that as part of the reaction for that to be an acceptable description. The decomposition part is not portrayed in your equation so you can't say that the equation contains decomposition. MathJax reference. which makes you more jittery coffee or tea? Is it important for a ethical hacker to know the C language in-depth nowadays? It does! It tends to coat the calcium carbonate surface, which prevents further reaction to take place. Where can I find an extensive list of the preferred chemical nomenclature? Making statements based on opinion; back them up with references or personal experience. Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. What does “blaring YMCA — the song” mean? While double replacement is correct, you could also classify it as a neutralization reaction (what I think would be the most common answer if one had to pick a single description).
