Some acid questions, true of false?

1] Weak acids and bases are used to washed clothes





2] Acid preparation results mainly from combustion reactions





If they are wrong fix the sentence =D plz n tySome acid questions, true of false?
TRUE-Weak acids and bases are used to wash clothes. Sodium Carbonate and hypochlorous acid or oxalic acid are examples.





TRUE-Hydrating the product of non-metal combustion is the route to most mineral acids, sulfuric, carbonic, phosphoric. Halogen acids like HCl are not made this way. Organic acids result from oxidation, a process similar to combustion.





For example, burning sulfur creates SO2, which treated with a catalyst (VO5), and oxygen, then water gives sulfuric acid. Sulfuric acid tops the list of acids and inorganic chemicals. For many years, H2SO4 production or use has been the benchmark for a country's industrial status.Some acid questions, true of false?
Of course you do not use strong acids or bases to wash your clothes. They'd be destroyed. The main base used in powdered laundry soap is sodium carbonate.





The second one seems weird. Combustion of a hydrocarbon gives CO2 and water, which could combine back to give carbonic acid. Combustion of sulfur (and phosphorus and other nonmetals) gives sulfur oxides (and other nonmetal oxides) which are acidic anhydrides. But combustion of a metal like magnesium will give an oxide that is a basic anhydride.
1] True. Most often, a base is used. The most common one you will find in laundry detergent is NaCO3 (Sodium Carbonate)





2] Sort-of. Combustion is oxidization, only when energy is required/released (see endothermic vs. exothermic). A good example of oxidization without combustion is rust: Iron oxide.


The only acid that can result from a combustion is Carbonic Acid (H2CO3). Other Acids can be produced from the oxidization of other substances (eg. salt with sulfuric acid will give you hydrochloric acid)
1) False. Basic surfactants are used to wash clothes.


2) False. Carbon dioxide and waterresults from combustion reactions
