Effect of Differences of HCl Concentration on the Reaction of Chlorine Gas and Acetylene Gas In Clothing Liquids and Floor Cleaning Liquids

Abstract

Floor cleaning fluid containing a solution of HCl mixed with carbide (CaC2), produces a reaction in the form of gases, air bubbles and there is sedimentation. The resulting gas is acetylene gas. NaClO solution in clothes bleach reacts with HCl in floor cleaning fluid to produce a reaction in the form of an explosion of fire, soot / carbon and produces chlorine gas. This study aims to determine the effect of differences in the concentration of HCl in floor cleaning fluid to produce the reaction of chlorine gas and acetylene gas by mixing floor cleaner with carbide and clothes bleach. In this study, using a floor cleaner with a concentration of 12% HCl and a concentration of 17% as a comparison. The results obtained are that the difference in the concentration of HCl has an effect on explosions, gases.

The Study of pH and Ionic Strength on Ni(II) and Pb(II) sorption using Humic Acid-Urea Formaldehyde (AHUF)

“…Berdasarkan perhitungan nilai kekuatan ion dan aktivitas ion (Tabel 2) diketahui bahwa nilai aktivitas ion Pb(II) dan Ni(II) pada konsentrasi 20 mg/L dalam sistem air masing-masing yaitu 0,9994 dan 0,9992 M, setelah penambahan NaCl 0,1 -0,5 M nilai kekuatan ion menurun hingga 0,3094 M. Data aktivitas ion Pb(II) dan Ni(II) menunjukkan bukti bahwa semakin besar konsentrasi NaCl dalam sistem adsorpsi, maka jumlah logam yang terserap semakin menurun. Hal ini disebabkan keberadaan Na(I) bersaing dengan Pb(II) dan Ni(II) dalam sistem adsorpsi 24,25 .…”
