H2SO4 + MnO2 + NaI = H2O + I2 + Na2SO4 + MnSO4. The limiting reagent row will be highlighted in pink. Input interpretation. Zn+CuCl2 -> ZnCl2+Cu HCl+NaOH -> H2O+NaCl 2CO+O2 -> 2CO2 SO3+H2O -> H2SO4 chemistry Ammonium bisulfide, NH2HS, forms ammonia NH3, and hydrogen sulfide, H2S through the reaction: NH4HS (s) NH3(g) + H2S(g) Kp value of .120 at 25C in a … This has already been discussed extensively over the past several months, principally considering HBr for bromosafrole but the considerations are the same or even more so for HI and iodosafrole. the hi produced will condense in the condenser and dirp in to the recieving that is being stirred in the ice bath. Please register to post comments. Password. One observation could be that, at the beginning, when NaI is in excess with respect to H 2 SO 4, only HI should form from the reaction, and when the amount of H 2 SO 4 increases, adding it drop by drop, HI then should react again with it forming I 2, SO 2 and H 2 O, so you should observe a change in colour of the mix, from white to yellow-brown, during the addition of the acid. © Copyright The Student Room 2017 all rights reserved. I understand that part, but then it says that HI can react further. Sulfuric acid - concentrated solution. This reaction takes place at a temperature of 30-50°C. 8 HI + H2SO4 (đặc, nóng) ==> H2S + 4 H2O + 4 I2. You can personalise what you see on TSR. but I have doubts about whether that's really the reaction that occurs. k2cr2o7 + 6 nai + 7 h2so4 → cr2(so4)3 + 3 i2 + 3 na2so4 + k2so4 Oxidation-Reduction K2Cr2O7 (aq) + 6 FeCl2 (aq) + 14 HCl (aq) → 2 CrCl3 (aq) + 2 KCl (aq) + 6 FeCl3 (aq) + 7 H2O (ℓ) H in H2S … Add / Edited: 22.06.2015 / Evaluation of information: 5.0 out of 5 / number of votes: 1. 2NaI + 2H2SO4 đặc —> Na2SO4 + SO2 + I2 + 2H2O. Substitute immutable groups in chemical compounds to avoid ambiguity. Chemist Hunter. 806 8067 22 Registered Office: International House, Queens Road, Brighton, BN1 3XE. ); The Gold Parsing System (Hats off! Help please😩, Edexcel AS/A Level Chemistry Student Book 1 Answers, EDEXCEL GCSE Chemistry 1CH0 - Paper 1 - 16th May 2019 [Unofficial Markscheme], How To Balance Cu + HNO3 = Cu(NO3)2 + NO + H2O, Official Dental Hygiene and Therapy applicants thread 2021. H2SO4is driped onto the salt. O in Na2SO4 is -2. I'm doing a question about reacting NaBr with H2SO4 (to write the equation), but I don't understand their answer In my text book (CGP) it's as follows (st Сoding to search: 2 NaBr + 3 H2SO4 = 2 NaHSO4 + Br2 + SO2 + 2 H2O. Balance the reaction of NaI + H2SO4 = I2 + H2S + H2O + Na2SO4 using this chemical equation balancer! This page describes and explains the redox reactions involving halide ions and concentrated sulphuric acid. In your half equations, you can probably discount sulphur dioxide and elemental sulphur. H in H2SO4 is +1. 8 NaI + 5 H2SO4 = 4 I2 + H2S + 4 Na2SO4 + 4 H2O There are three main steps for writing the net ionic equation for H2SO4 + NaOH = Na2SO4 + H2O (Sulfuric acid + Sodium hydroxide). Let us know your thoughts >>, Students to see questions before they sit them. Can anyone just give me the products? It uses these reactions to discuss the trend in reducing ability of the ions as you go from fluoride to chloride to bromide to iodide. Core Maths and GCSE Maths regarding university. a) 2 NaI +2 H2SO4 (đặc, nóng) ==> 2 NaHSO4 + 2 HI . H2SO4 (axit sulfuric)NaI (natri iodua) = H2O (nước)H2S (hidro sulfua)I2 (Iot)Na2SO4 (natri sulfat) | Phương Trình Phản Ứng Hóa Học. Make progress. Reaction stoichiometry could be computed for a balanced equation. What a great software product!) Tell us a little about yourself to get started. You'd probably get bits of sulphur dioxide and sulphur (oxidation states of +4 and 0 respectively), but like I said the I- can reduce it all the way to H2S (-2), so that would be the major product. It says: HI can be oxidised by the sulfuric acid to form I2, SO2 and H2S. the ionic equation is. Balance the reaction of NaI + H2SO4 = I2 + H2S + H2O + Na2SO4 using this chemical equation balancer! Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. ChemiDay you always could choose go nuts or keep calm with us or without. We have a brilliant team of more than 60 Support Team members looking after discussions on The Student Room, helping to make it a fun, safe and useful place to hang out.
