The reaction between zinc and hydrochloric acid is Zn + HCl = H2 + ZnCl2. It is a single replacement reaction where zinc metal displaces the hydrogen to form hydrogen gas and zinc chloride, a salt.Know More
Zinc reacts quickly with the acid to form bubbles of hydrogen. Carrying out the experiment in a closed sidearm flask allows collection of the gas in a balloon. Exposing the balloon to the heat of a lighted candle causes a rapid reaction, as the hydrogen reacts with oxygen to form water.
The zinc and hydrochloric acid reaction is an example of oxidation-reduction. The zinc metal begins the process as a pure metal with an ionic charge of zero and loses an electron as it reacts with the acid to become a positively charged zinc ion through oxidation. At the same time, hydrogen undergoes reduction by gaining an electron to become a neutral molecule.
Zinc is an important nutrient for animals and crops, including rice. In an application of the zinc and hydrochloric acid experiment, scientists have suggested adding weak hydrochloric acid to irrigation water. The acid reacts with zinc metal, found in the soil, to form zinc ions in a type the plant is able to use to improve crop yields.Learn more about Solutions & Mixtures
Zinc nitrate is commonly used in the manufacture of inorganic zinc compounds ranging from catalysts to pigments and mordant in dyeing. This compound is also used in the manufacturing of medicines. Zinc nitrate solution is used as a foliar spray, and it is also added to irrigation water or liquid fertilizer for soil application. Zinc nitrate is an excellent precursor for the production of high-purity compounds and nanoscale materials.Full Answer >
The reaction between sulphur and oxygen is a chemical reaction in which, with gentle heating, sulphur burns in oxygen to produce colorless sulphur dioxide gas. It burns with a pale blue flame.Full Answer >
The reaction between KHP and NaOH is shown by the balanced equation KHC8H4O4 + NaOH = NaKC8H4O4 + H2O. KHP stands for potassium hydrogen phthalate, which has the chemical formula KHC8H4O4.Full Answer >
Acetone dissolves in water, and there is minimal chemical reaction involved. As acetone is dissolved in water, hydrogen bonds form between the molecules of water and acetone. The hydrogen bonds are what keeps the acetone dissolved in the water.Full Answer >
