Explain the role of water in dissociation of acids and bases.
. This leads to the evolution of hydrogen gas. Hydrogen gas can be a problem with carbon steel in sulphuric acid environments because it can literally scrub off the mechanically weak iron sulphate film which is the only thing protecting the steel from attack. The acid that conducts electricity strongly is a strong acid and the acid that conducts electricity weakly is a weak acid.
Battery acid is a common name for sulfuric acid US or sulphuric acid UK. Set the apparatus as shown in the Fig. Bring a burning match stick near the mouth of the test tube Fig.
7 to 14. Sulfuric acid is a mineral acid with the chemical formula H 2 SO 4. 0 to 14 D.
Battery acid is highly corrosive and able to cause severe burns. Calcium carbonate is produced B. Range of pH scale is A.
Due to excess passing of CO2 through an aqueous solution of slaked lime its milkiness fades because A. Calcium bi-carbonate is produced C. 0 to 10 C.
Calcium oxide is produced D. Differentiate between strong and weak acids and bases. Reactions of Acids and Bases with Metals.
Chemical Properties of Acid and Bases 1. Sulphuric acid carefully along the sides of the test tube. Due to the production of.
During periods of normal flow the gas bubbles. The iron sulphate film is relatively weak and can be disturbed by high acid velocities or other disturbances in the liquid. In lead-acid batteries the concentration of sulfuric acid in water ranges from 29 to 32 or between 42 molL and 50 molL.
7 to 10 B. When a metal reacts with an acid it generally displaces hydrogen from the acids.
