Sulfuric acid and Sodium hydroxide Hello,you are in right place to know about the reaction between sulfuric acid and sodium hydroxide. Sulfuric acid is an acid because it has hydrogen ion.The formula for sulfuric acid is H₂SO₄.It is a strong acid. Sodium hydroxide is a base because it has hydroxide ion.The chemical formula for sodium hydroxide is NaOH.It is a strong base. Read this:CO Lewis Structure Sulfuric acid(H2SO4) and Sodium hydroxide(NaOH) Acid reacts with base to form salt and water.This type of reaction is called acid base neutralization reaction. In case of sulfuric acid and sodium hydroxide,acid-base neutralization reaction will happen. Sulfuric acid reacts with sodium hydroxide and produce sodium sulphate(Na₂SO₄) and water(H₂O).Here sodium sulphate(Na₂SO₄) is a salt beacause its positive part has come from base and negative part has come from acid. H₂SO₄ +2 NaOH =Na₂SO₄ +2H₂O Which salt is produced

【】How to Convert Ethene to Ethanoic Acid or Acetic Acid||How Ethanoic Acid Is Prepared from Ethene
How to Convert Ethene to Ethanoic acid or Acetic Acid Answer: To convert ethene to ethanoic acid,we will adopt four steps: Step-1: Ethene reacts with HBr and we get 1-bromo ethane. Step-2: 1-bromo ethane reacts with aqueous KOH and we get ethanol. Step-3: Ethanol is oxidized by K₂Cr₂O₇ plus H₂SO₄ and we get ethanal. Step-4: Again,ethanal is oxidized by K₂Cr₂O₇ plus H₂SO₄ and we get ethanoic acid or acetic acid. Now see all the steps at a glance.

August 19, 2022
How to Convert Propyne to Propene Propyne reacts with hydrogen (H₂) in presence of Pd and BaSO₄ at 25ºc temperature and produce propene(CH₃-CH=CH₂). Here BaSO4 acts as catalyst poison towards Pd catalyst reducing it's catalytic action and controls the upto first stage. How to Convert Propene to Propyne Step-1: Propene(CH₃-CH=CH₂) reacts with Br₂ in presence of CCl₄ and produce 1,2-dibromo propane( CH₃-CH(Br)CH₂Br). Step-2: 1,2-dibromo propane( CH₃-CH(Br)CH₂Br) reacts with (alc)KOH and produce 1-bromo propene-1(CH₃-CH=CH-Br). Step-3: 1-bromo propene-1(CH₃-CH=CH-Br) reacts with sodamide and produce propyne.

SO2 Lewis Structure Answer: Here is the definition of SO2 Lewis structure. SO2 Lewis structure (sulfur dioxide electron dot structure) is that type of diagram where we show the total 18 valence electrons of SO2 as dotns , or dots and dashes(-).In Lewis structure,it is common that a bonding pair of two electrons can be shown by dash(-) or dots(●●) but a lone pair of two electrons is shown by dots<●●>. In SO2 Lewis structure,there are two double bonds that are going from the atom sulphur to oxygens. In SO2 Lewis structure ,there are totally five lone pairs of electrons.The each oxygen has two lone pairs of electrons and the sulphur atom has one lone pair of electrons. In SO2 Lewis framework ,the oxygen atoms follow the octet rule but the sulfur atom don't follow the octet rule.It has more than eight electrons. In SO2 Lewis structure,we get nine pairs of electrons.Out of nine pairs of electrons,SO2 has four bond pairs of electrons and five lone pairs of electrons.Here,each oxy
