Hydrochloric Acid and Sodium Hydroxide Hello,you space in right ar to know about the reaction between hydrochloric acid and also sodium hydroxide. Hydrochloric acid is one acid because it has hydrogen ion.The formula because that hydrochloric mountain is HCl.It is a solid acid. Salt hydroxide is a base since it has hydroxide ion.The chemistry formula for sodium hydroxide is NaOH.It is a solid base. Hydrochloric acid (HCl) and also Sodium hydroxide(NaOH) acid reacts with base to type salt and also water.This form of reaction is referred to as acid base neutralization reaction. In case of hydrochloric acid and sodium hydroxide,acid-base neutralization reaction will happen. Hydrochloric acid reacts v sodium hydroxide and produce sodium chloride(NaCl) and also water(H₂O).Here salt chloride(NaCl) is a salt beacause the positive component (Na+)has come from base and an adverse part(Cl-) has come from acid.

【】How to transform Ethene to Ethanoic acid or Acetic Acid||How Ethanoic acid Is all set from Ethene


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

just how to transform Propyne come Propene Propyne reacts through hydrogen (H₂) in visibility 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 reducing it's catalytic action and controls the upto an initial stage. Just how to transform Propene to Propyne          Step-1: Propene(CH₃-CH=CH₂) reacts through Br₂ in presence of CCl₄ and also produce 1,2-dibromo propane( CH₃-CH(Br)CH₂Br).             Step-2: 1,2-dibromo propane( CH₃-CH(Br)CH₂Br) reacts through (alc)KOH and also produce 1-bromo propene-1(CH₃-CH=CH-Br).                        Step-3: 1-bromo propene-1(CH₃-CH=CH-Br) reacts with sodamide and also produce propyne.

SO2 Lewis Structure   Answer: below is the meaning of SO2 Lewis structure. SO2 Lewis framework (sulfur dioxide electron dot structure) is that type of diagram where we present the complete 18 valence electrons of SO2 as dots , or dots and dashes(-).In Lewis structure,it is usual that a bonding pair of two electrons deserve to be shown by  dash(-) or dots(●●) however a lone pair of 2 electrons is shown by dots<●●>. In SO2 Lewis structure,there space two dual bonds that room going indigenous the atom sulphur come oxygens. In SO2 Lewis framework ,there are totally five lone pairs of electrons.The each  oxygen has two lone pairs of electrons and also the sulphur atom has one lone pair the electrons. In SO2 Lewis structure ,the oxygen atom follow the octet rule yet the sulfur atom don't monitor 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 bag of electrons.Here,each oxy
