Check if the given hydrated cation reacts with water to give an acidic solution. If so, write the chemical equation for the reaction. (Be(H2O)4)2+Carbon dioxide can dissolve in water to form carbonic acid. Write the chemical equation showing this reaction.Writ...
The fizz produced when an Alka-Seltzer tablet is dissolved in water is due to the reaction between sodium bicarbonate (NaHCO3) and citric acid (H3C6H5O7): 3NaHCO3(aq)+H3C6H5O7(aq) yields When sodium bicarbonate and citric acid are mixed together, the solution becomes cooler. Is this...
Look out for any cloudiness or white deposits at the bottom of your container — this tells you some minerals didn’tdissolve, or reacted together to form something that doesn’tdissolve, which will throw off your calculations. Lastly, a warning: don’t put remineralised water in your espr...
