Sulfate attack in concrete Understanding CementCAUSES OF COPPER CORROSION IN PLUMBING SYSTEMS

Sulfate attack in concrete and mortar Sulfate attack can be external or internal External due to penetration of sulfates in solution in groundwater for example into the concrete from outside Internal due to a soluble source being incorporated into the concrete at the time of mixing gypsum in the aggregate for example External sulfate attack This is the more common type and circumstances the attack would almost certainly not occur In the past corrosion of lead pipes was a major issue for human health as was the use of leaded solders

Dissolution of iron oxide using oxalic acid ScienceDirectWebElements Periodic Table Aluminium reactions of elements

Non hematite iron oxides in the iron rust were found to dissolve faster than hematite confirming previous studies by other workers At the stoichiometric ratio oxalate/iron oxide of 5 1 as per EqThe surface of aluminium metal is covered with a thin layer of oxide that helps protect the metal from attack by air So normally aulumium metal does not react with air If the oxide layer is damaged the aluminium metal is exposed to attack even by water

Sodium hydroxide WikipediaThe Effects of Acid on Different Kinds of Metal Sciencing

Sodium hydroxide does not attack iron at room temperatures since iron does not have amphoteric properties ie it only dissolves in acid not base Nevertheless at high temperatures eg above 500 176 C iron can react endothermically with sodium hydroxide to form iron III oxide sodium metal and hydrogen gas 21 The noble metals are at the other extreme they are resistant to corrosion in moist air and do not react readily with dilute or weak acids Gold for example does not even react with nitric acid a strong oxidizing agent although it will dissolve in aqua regia a solution of

Although Fe 2 is very soluble Fe 3 will not dissolve appreciably If the groundwater is oxygen poor iron and manganese will dissolve more readily particularly if the pH of the water is on the low side slightly more acidic Dissolved oxygen content is typically low in deep aquifers particularly if the aquifer contains organic matter Decomposition of the organic matter depletes the However iron phosphate is not likely to be inhaled This is because it is made in a granular form and does not release vapors into the air This is because it is made in a granular form and does not release vapors into the air
