A cotton swab is dipped into concentrated hydrochloric acid (producing hydrogen chloride gas) while a second on is dipped into concentrated aqueous ammonia (producing ammonia gas). Both cotton swabs ...

Essentially, 100% of the protons are transferred to water in an aqueous solution of hydrochloric acid, leaving only chloride anions (Cl –) behind and drastically increasing the hydronium ion ...

it's at a low enough concentration where it's not going to hurt you,” he said. It has been less than two years since a much ...

If the hydrogen ion concentration increases by a factor of 100 (10 2), the pH decreases by 2. A solution of 0.8 mol/dm 3 hydrochloric acid has a pH of 0.1. Predict its pH when it is diluted to 0. ...

Mix one part hydrochloric acid with 10 parts water to obtain the desired concentration of acid for household cleaning purposes. Bonus tip: Always remember to pour acid into water, not water on acid.

The sodium reacts most vigorously with the nitric acid, producing a flame and smoke. The sodium also reacts pretty strongly with the weaker concentration of hydrochloric acid. The demonstration shown ...
