You have a titanium tank in your plant which is used to store 10% muriatic acid(commercial low cost hydrochloric acid), which contains a supplied 0.5% ferric chloride as an impurity. Careful measurements have shown that the tank is resistant to this media because it spontaneously passivates. Explain the following using appropriate polarization diagrams if necessary.(a) Your supplier offers you some 10% muriatic acid containing 2% ferric chloride at a bog discount because other consumers reject it on the basis of its deep orange colour. If ferric salts are tolerable in your process, will this acid corrode your tank more rapidly than the regular muriatic acid? (b) An excess of pure hydrochloric acid with no ferric salts becomes available from another part of the plant. Can you take this acid into your storage tank without any risk of increasing corrosion rate?
