Vinegar

CH3COOH+NaHCO3 -> H2O+NaOCOCH3+CO2

Because the acetic acid in the vinegar reacts with the solid calcium carbonate crystals that make up the eggshell, separating them into their calcium and carbonate parts, the calcium ions floats free and the carbonate makes the bubbles (carbon dioxide) that you can see on the egg. The protein that binds the calcium and carbonate is the froth that you can see on the top.

How does vinegar clean coins?

The neutralization reaction between the sodium bicarbonate which is the baking soda and the acetic acid in the vinegar results in water and sodium acetate. Sodium acetate is a salt that is rather soluble in water, so it dissolves to form a clear solution.

Polish remover evaporates faster than vinegar because its boiling point is 78 degrees Celsius and it's lesser than vinegar because its 118 degrees Celsius.

yes.
Distilled vinegar contains minute amounts of sodium chloride, commonly known as table salt. But the amount present is often in very small amounts compared to other types of vinegars, and would hardly affect the sodium intake if consumed as per normally.

Baking soda and vinegar gets cold in a reaction called an endothermic reaction. Ectothermic reactions get warm, endo cold. All the heat is taken in by the baking soda and used as energy. If you add more baking soda, more baking soda will take in energy and make it colder.

Actually, lactic acid encompasses a vast array of species of bacteria. It is used in food production such as yogurt and sauerkraut, fermented foods, etc. It lowers the pH of the food/beverage thus preventing growth of other bacteria. It does occur naturally as a byproduct of strenuous muscle activity, however it is commonly created for industrial use by fermentation of corn.

Vinegar is a solution of acetic acid dissolved in water.

Yes, but the flavor will be a little different.

They dont exactly melt. Only natural ones will tend to dissolve in white distilled vinegar due to the acidicity.

Some people use this method, to check whether the pearl is a fake or not.

There are 59.5 mmols of baking soda and 167 mmols of vinegar. The reaction of the two substances is NaHCO3(s) + CH3COOH(l) = CO2(g) + H2O(l) + Na+(aq) + CH3COO-(aq). This means the limiting reactant is baking soda, and 2.62 grams of CO2 is produced.

If the mortar which has dried upon the brick is a Portland Cement mortar there is no sure fire way to remove it. As a professional mason I tell my customers that we can reduce the degree of mortar staining but seldom can we eliminate it. We use Muriatic Acid mixed with water 1:10. That's 1 part muriatic acid to 10 parts water. You can buy Muriatic acid at most Home Improvement stores as it is commonly used in swimming pools. Wear chemical proof gloves and eye goggles. Use a mason's sponge, a stiff nylon brush and a good "putty" knife. Soak the dried mortar with the 1:10 mixture using the sponge. Scrub with the nylon brush. Use the putty knife to carefully scrape away anything larger than an "film". If this does not result in the removal increase the strength of the acid gradually but do not exceed 1:5. The acid will burn the brick if it is used too strong or left to sit on the brick too long. Have a bucket of clean water with a mason's sponge close at hand to neutralize the acid once your scrubbing has been completed. Be careful where the acid and water mixture is allowed to "run off". It will kill plants and harm most surfaces. Consult local codes before you attempt this method to determine where you can safely dispose of the mixture.

Vinegar is produced by acetic acid producing bacteria during the fermentation of wine, cider, or beer, and is used as a condiment or for pickling.

yes

, because the vinegar and baking soda create pressure. You can create an 'Otto Cycle' motor - works just like a car's motor, except that instead of ignition, you would need to introduce the materials into the reaction chamber. All that's needed is a small enough amount of the two reactants, which would then push a piston. Once the reaction is done, you would need to remove the excessive water and co2 vapor. This would be done by opening valves. In most motors a flywheel is used to mechanically get the motor moving.

I have searched for this, but have not seen it done.

They could have eaten fries with vinegar on them.

No,red wine vinegar does not contain any sugar.

Yes, baking soda is antibacterial. The component that makes it antibacterial is sodium bicarbonate. It is also an antimicrobial and antifungal.

Is the Test tube sealed airtight or open air? Dissolving is a physical change.

Vinegar is an acid and sodium bicarbonate is a base. The acid reacts with sodium bicarbonate causing the release of carbon dioxide gas. The water is probably only there to dilute the other reactants, to make it less vigorous.

The penny will get clean i did that in science class and in less than 2 minutes the penny became clean

common malt vinegar is made of ethanoic acid == ==

yes it does, all you need is:

bottled water

apple cider vinegar

paper towel.

wash your face with a kind of cleanser or soap just to get rid of all the oils and dirt on your face .pour two table spoons of acv (apple cider vinegar) and pour more water than you did acv. now take the paper towel and fold it into a square shape. dip the paper towel you folded into the acv and water and pat it on your face not rub or scrub. pat it on the affected areas and leave it on overnight and wake up and wash it off. it might smell bad but after a couple of nights and hours it wont seem so bad. you will see results in about 3 days every morning.

It would fizz up and in a couple of days white hard stuff will grow on it.

I have no idea i am looking for help.
