## How do you measure the rate of reaction between calcium carbonate and hydrochloric acid?

Method

1. Support a gas syringe with a stand, boss and clamp.
2. Using a measuring cylinder, add 50 cm 3 of dilute hydrochloric acid to a conical flask.
4. Every 10 seconds, record the volume of gas produced.
5. When the reaction is complete, clean the apparatus as directed by a teacher.

## What type of reaction is CaCO3 and HCl?

This is an acid-base reaction (neutralization): CaCO3 is a base, HCl is an acid.

Is HCl and CaCO3 a first order reaction?

The reaction of calcium carbonate with hydrochloric acid is said to be first order with respect to hydrochloric acid. This is because the rate depends upon the concentration of hydrochloric acid to the power one. n is the order of the reaction with respect to A and m is the order of reaction with respect to B.

### How do you calculate the initial rate of reaction in chemistry?

The initial rate is equal to the negative of the slope of the curve of reactant concentration versus time at t = 0….The rate of a reaction is expressed three ways:

1. The average rate of reaction.
2. The instantaneous rate of reaction.
3. The initial rate of reaction.

### How do you calculate the rate of a chemical reaction?

For a reaction of A → B the reaction rate is (change of concentration)/time. If plotted on a graph, the concentration of A would decrease over time and the concentration of B would increase. The gradient of the graph indicates the rate of reaction – the steeper the gradient the faster the rate of reaction.

What is the balanced equation for CaCO3?

#### Is HCl first order?

This corresponds to [HCl] falling from 0.5 mol dm-3 to 0.25 mol dm-3. The half-life for this is 147 seconds. The half-lives for the three different parts of the equation are roughly the same; they are independent of the starting concentration of HCl. Therefore the reaction is first order with respect to [HCl].

#### What is the chemical formula of hydrochloric acid?

HClHydrochloric acid / Formula

What ion is CaCO3?

calcium ion
Calcium carbonate (CaCO3) has ionic bonding between calcium ion Ca2+ and a polyatomic ion, CO2−3, but within the carbonate ion (CO32-), the carbon and oxygen atoms are connected by covalent bonds (shown above).

## How to determine the rate of reaction between CaCO3 and HCl?

To investigate the rate of reaction between Calcium Carbonate (CaCO3) and Hydrochloric Acid (HCl) by changing the molarity of the acid and measuring how much time it took for reacting in each test. Predicted that the higher molar concentration of the acid the faster the reaction will take place.

## What is the chemical equation for calcium carbonate and HCl?

Calcium carbonate (CaCO3) reacts with stomach acid (HCl, hydrochloric acid) according to the following equation:CaCO3(s)+2HCl (aq)?CO2 (g)+H2O (l)+CaCl2 (aq)Tums, an antacid, contains CaCO3. Similarly, it is asked, what is the reaction between calcium carbonate and hydrochloric acid?

What is the equation for Tums CaCO3 aq and HCl aq?

What is the equation for the reaction between Tums CaCO3 AQ and the HCl AQ in stomach acid? Calcium carbonate (CaCO3) reacts with stomach acid (HCl, hydrochloric acid) according to the following equation:CaCO3(s)+2HCl (aq)?CO2 (g)+H2O (l)+CaCl2 (aq)Tums, an antacid, contains CaCO3.

### Why does CaCO3 not dissolve in water?

Why does CaCO3 not dissolve in water? Simply because the electrostatic bonds between the carbonate anion and the calcium ion are too strong to be overcome by solvation by water molecules. What are the products of CaCO3 and HCl? Calcium carbonate reacts with hydrochloric acid to form calcium chloride, water and carbon dioxide.
