Answers
Hello dear
your answer is option A
Answer:
Explanation:
Sodium hydroxide:
Lye and caustic soda are other names for sodium hydroxide, an inorganic substance having the formula NaOH. It is a white, solid ionic substance made up of the cations sodium (Na+) and the anions hydroxide (OH).
At normal ambient temperatures, sodium hydroxide, a highly caustic base and alkali, breaks down proteins and can result in serious chemical burns. It easily collects moisture and carbon dioxide from the air due to its high water solubility. It produces a string of NaOH-nH2O hydrates. From water solutions, the monohydrate NaOHH2O crystallizes between 12.3 and 61.8 °C. This monohydrate is frequently the "sodium hydroxide" sold commercially, and it may be used in published data instead of the anhydrous substance.
In order to show chemistry students the pH scale, sodium hydroxide, together with neutral water and acidic hydrochloric acid, is usually used as one of the simplest hydroxides.
Numerous industries use sodium hydroxide, including those that produce pulp and paper, textiles, drinking water, soaps and detergents, and drain cleaners. Around 60 million tonnes were produced globally in 2004, compared to 51 million tonnes of demand.
