a dilute ferrous sulphate solution was gradu¬ally added to the beaker containing acidified permanganate solution. the light purple colour of the solution fades and finally disap¬pears. which of the following is the correct explanation for the observation? (a) kmno4 is an oxidising agent, ...
KMnO4, OH-, H2O Draw the product formed when cyclohexene undergoes a reaction with cold, dilute basic solution of KMnO_4. 1. Write down the reaction mechanism for the dehydration of cis-2-methylcyclohexanol via E2 pathway. 2. Write the reacton equations between 1-methylcyclohexan...
The reaction studied during this experiment will be the reaction of oxalic acid with permanganate (KMnO4). The reaction is as follows: 3H_2C_2O_4 (aq) + 2MnO-_4 (aq) ---> 6CO_2 (g) + 2Mno_2 (s) + 2O Su...
To calculate the stoichiometry of H3PO3 + KMnO4 + HNO3 = H3PO4 + Mn(NO3)2 + KNO3 + H2O you must balance the equation to find the stoichiometric mole ratio of each compound. The equation can be balanced using the chemical equation balancer. The ...
Write the dissociation reaction and the corresponding Ka equilibrium expression for each of the following acids in water. (For the dissociation reaction, include states-of-matter under the given condi Write the equation for the dissociation of KMnO4 in water. Write a balanced equation to re...
不需要复合状态[如(s)(aq)或(g)]。 你可以用小括号()或括号[ ]。 例子 I2 + NaOH = NaI + NaIO + H2O FeCl2 + O2 + H2O = Fe2O3 + HCl NO3 + Na2 = NaNO3 CrCl3 + MnO2 + H2O = MnCl2 + H2CrO4 KMnO4 + HCl + H2S = MnCl2 + KCl + S + H2O ...
