【●】H2SO4 + NaOH ||Sulfuric acid(H2SO4) and Sodium hydroxide(NaOH)--What is the reaction in between sulfuric acid and also sodium hydroxide?


Sulfuric acid and Sodium hydroxide Hello,you room in right place to know around the reaction in between sulfuric acid and sodium hydroxide. Sulfuric acid is an acid since it has hydrogen ion.The formula because that sulfuric mountain is H₂SO₄.It is a solid acid. Salt hydroxide is a base since it has hydroxide ion.The chemical formula for salt hydroxide is NaOH.It is a solid base. Check out this:CO Lewis structure                 Sulfuric acid(H2SO4) and Sodium hydroxide(NaOH)  Acid reacts through base to form salt and water.This type of reaction is referred to as acid base neutralization reaction. In instance of sulfuric acid and also sodium hydroxide,acid-base neutralization reaction  will happen. Sulfuric mountain reacts v sodium hydroxide and produce salt sulphate(Na₂SO₄) and also water(H₂O).Here  sodium sulphate(Na₂SO₄) is a salt beacause the positive part has come from basic and negative part has come native acid. H₂SO₄ +2  NaOH =Na₂SO₄ +2H₂O i m sorry salt is produced

Hydrochloric Acid and also Sodium Hydroxide Hello,you are in right location to know around the reaction between hydrochloric acid and sodium hydroxide. Hydrochloric acid is an acid because it has actually hydrogen ion.The formula because that hydrochloric mountain is HCl.It is a solid acid. Salt hydroxide is a base due to the fact that it has actually hydroxide ion.The chemistry formula for sodium hydroxide is NaOH.It is a strong base. Hydrochloric mountain (HCl) and also Sodium hydroxide(NaOH) mountain reacts v base to kind salt and water.This type of reaction is dubbed acid base neutralization reaction. In instance of hydrochloric acid and also sodium hydroxide,acid-base neutralization reaction will happen. Hydrochloric acid reacts with sodium hydroxide and produce salt chloride(NaCl) and water(H₂O).Here sodium chloride(NaCl) is a salt beacause its positive component (Na+)has come from base and an unfavorable part(Cl-) has come from acid. HCl+ NaOH =NaCl +H₂O Hydrochloric Acid and also Sodium Hydroxide balanced Equation now I will balance hydrochlor

【】How to convert Ethene come Ethanoic acid or Acetic Acid||How Ethanoic mountain Is ready from Ethene


How to convert Ethene come Ethanoic acid or Acetic mountain Answer: To transform ethene come ethanoic acid,we will adopt four steps:              Step-1: Ethene reacts through HBr and also we acquire 1-bromo ethane.            Step-2: 1-bromo ethane reacts through aqueous KOH and we get ethanol.            Step-3: Ethanol is oxidized through K₂Cr₂O₇ plus H₂SO₄ and we acquire ethanal.            Step-4: Again,ethanal is oxidized by K₂Cr₂O₇ to add H₂SO₄ and we gain ethanoic mountain or acetic acid. Now see all the measures at a glance.

【】How to transform propene come propyne and also propyne come propene conversion


August 19, 2018
just how to transform Propyne come Propene Propyne reacts v hydrogen (H₂) in existence of  Pd and also BaSO₄ in ~ 25ºc temperature and also produce propene(CH₃-CH=CH₂). Right here BaSO4 acts as catalyst poison towards Pd catalyst to reduce it's catalytic action and controls the upto first stage. Just how to transform Propene come Propyne          Step-1: Propene(CH₃-CH=CH₂) reacts through Br₂ in existence 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 also produce 1-bromo propene-1(CH₃-CH=CH-Br).                        Step-3: 1-bromo propene-1(CH₃-CH=CH-Br) reacts v sodamide and produce propyne.

SO2 Lewis Structure   Answer: here is the meaning of SO2 Lewis structure. SO2 Lewis framework (sulfur dioxide electron dot structure) is that kind of diagram whereby we display the complete 18 valence electrons of SO2 together dots , or dots and also dashes(-).In Lewis structure,it is usual that a bonding pair of 2 electrons deserve to be presented by  dash(-) or dots(●●) yet a lone pair of 2 electrons is presented by dots<●●>. In SO2 Lewis structure,there are two twin bonds that are going from the atom sulphur come oxygens. In SO2 Lewis framework ,there are totally five lone bag of electrons.The each  oxygen has two lone bag of electrons and also the sulphur atom has one lone pair of electrons. In SO2 Lewis structure ,the oxygen atom follow the octet rule but the sulfur atom don't follow the octet rule.It has an ext than eight electrons. In SO2 Lewis structure,we obtain nine bag of electrons.Out of ripe pairs the electrons,SO2 has four bond bag of electrons and five lone bag of electrons.Here,each oxy
