Which of the following is not a correct acid-base neutralization reaction? hi + koh --> ki + h20 ca(oh)2 + hcl --> cacl + h2o ch3cooh _ nh4oh --> nh4ch3coo + h2o hbr _ csoh --> csbr + h2o

Ca(OH)2  + HCl →  CaCl  + H2O   is  not a correct acid- base  neutralization reaction

    Explanation

 Acid and base react to form   salt and water.

The  reaction of Ca(OH)2 + HCl →  CaCl2 +H2O  is not  correct  because  

Therefore the correct acid -base  neutralization  reaction  is as below

Ca(OH)2  + 2HCl→  CaCl2   + 2H2O

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
