1. Define an superman. Give the names and formula of 5 sodding(a) pane of glasss Arrhenius hypothesis shows us that acids atomic number 18 sources of H ions in sedimentary solution and in Brønsted-Lowry surmise an acid is a nubble that donates protons. Or the Lewis system We argon inclined to judge of hearts as possessing acid or basic properties, without having a accompaniment solvent in mind. An acid is i which can mesh a lone match from another molecule in completing the stable convocation of one of its own atoms. The first-year dickens theories, Arrhenius and Brønsted-Lowry are to do with the protons; exchange in the midst of substances, the Lewis however looks at the electron arrangement of the substance. Acetic acid HC2H3O2 acetate carbonous acid H2CO3 carbonate Hydrochloric acid HCl chloride Nitric acid HNO3 treat phosphorous acid H3PO4 phosphate Sulphuric acid H2SO4 sulphate 2. Give 3 vulgar properties of acids Turn s blue litmus florid Conducts an electric current Taste sour Reacts with metals to dos hydrogen bobble Reacts with carbonate and hydroen-carbonates to form carbon dioxide gas Reacts with Metal oxides to fix a coarseness and water React with metal hydroxides to produce a salt irrefutable water 3. Define a derriere.
Give the names and formula of 4 common bases Arrhenius theory says that a base is a substance which a produces hydroxide ions in aqueous solution. Brønsted-Lowry theory states that a base is an electron acceptor. It seems to me that with release generality we whitethorn say that a basic substance i s one which has a lone pair of electrons whi! ch may be used to complete the stable convention of another atom. In both acids and bases, the solutions are not one substance but they are slipt into the two ions. Such as HCl > H+ + Cl- and NaOH > Na+ + OH- this means that a bottle of NaOH or HCl does not occur however the ions of the substance are in the bottle. Sodium hydrated oxide - NaOH Potassium hydroxide - KOH Ammonium Hydroxide - NH4OH Calcium Hydroxide - Ca (OH) 2...If you pauperization to get a full essay, order it on our website: BestEssayCheap.com
