If the stone is acid safe, soak it in vinegar for a couple of days to dissolve carbonate deposits. You can check to see if it will react with vinegar by adding a few drops of vinegar to the stone’s surface and waiting. If it hasn’t started bubbling within 10 minutes or so, it should be safe.

Sidewalk chalk contains a compound called calcium carbonate (CaCO3), which reacts with vinegar (acetic acid, CH3COOH) to form the gas carbon dioxide (CO2). This is because the reaction needs to have vinegar and chalk molecules colliding together to complete.

Calcite is typically found in the sedimentary rock called limestone. When you place a drop of weak acid, such as vinegar, on calcite, it will bubble. This happens because a reaction causes a little bit of the calcite to break down, releasing carbon dioxide gas, making the bubbles.

What to think about: What happens when you put lemon juice on each rock? These mild acids can dissolve rocks that contain calcium carbonate. The lemon juice and vinegar should have bubbled or fizzed on the limestone, calcite, and chalk, which all contain calcium carbonate.

Vinegar is an acid called acetic acid. When it combines with calcium carbonate in eggshell and in the antacid tablet, a chemical reaction takes place. In the reaction, the atoms in the acetic acid and the calcium carbonate come apart and rearrange in different ways to make new chemicals.

Apple cider vinegar, a fermented vinegar that people make from crushed apples, is a popular natural remedy for acid reflux and heartburn. Many home remedies can successfully alleviate the symptoms of acid reflux, heartburn, and other symptoms of gastroesophageal reflux disease (GERD).

Does an antacid tablet dissolve faster in hot or cold water? (Answer: Hot; it has more energy to react with the antacid.) It has more energy in the form of water molecules that vibrate and move around faster than those in cold water.

Antacid tablets are generally taken to relieve an upset stomach and contain sodium bicarbonate, citric acid, and sometimes, pain relievers. The tablets dissolve in water, and the contents are swallowed as part of the solution.

Water had the fastest average dissolving time (63 seconds) while Sprite had the slowest dissolving time (86 seconds).

Gases dissolve in cold liquids better because warm liquid will have its molecules more excited, therefore moving faster and not being able to hold onto the dissolved gasses.

What happens when you stir a spoonful of sugar into hot water? The sugar dissolves into the water. The water tastes sweet and may appear slightly cloudy. [You can boil or evaporate the water to see solid sugar again.]

When you stir a spoonful of sugar into a glass of water, you are forming a solution. This type of liquid solution is composed of a solid solute, which is the sugar, and a liquid solvent, which is the water. As the sugar molecules spread evenly throughout the water, the sugar dissolves.

the water and the sugar particles will be mix together and form a new substance. Because the sugar has dissolved in the water, it’s not clumped at the bottom of the cup nor has it turned into water or is just floated around the cup.

Answer: Yes heating water allows it to dissolve more Sugars because the molecular distance increases and this distance can be covered by more sugar. In the given question, The independent variable would be the temperature of water.

The solubility of O2 changes with temperature, salinity and pressure. The solubility of O2 in water increases as the temperature decreases, meaning that cold water can hold more O2. For example, cold water at 5°C (12.8 mg/L) holds about 55% more dissolved oxygen than warm water at 25°C (8.3 mg/L)[1].
