A neutralization reaction is a type of double replacement reaction. A neutralization reaction occurs when an acid reacts with an equal amount of a base. This reaction usually produces a salt. One example, hydrochloric acid reacts with disodium iron tetracarbonyl to produce the iron dihydride: 2 HCl + Na 2 Fe(CO) 4 → 2 NaCl + H 2 Fe(CO) 4
When attempts to produce sulfur iodide by the direct combination of the elements failed to overcome the low thermodynamic stability of the compound, production by double replacement was attempted between 1833 and 1886. Some reactions that were attempted was the reaction of disulfur dichloride and hydroiodic acid: [2] S 2 Cl 2 + 2 HI → S 2 I 2 ...
Reaction with hydrogen sulfide produces barium sulfide. Precipitation of many insoluble, or less soluble barium salts, may result from double replacement reaction when a barium hydroxide aqueous solution is mixed with many solutions of other metal salts. [17] Reactions of barium hydroxide with ammonium salts are strongly endothermic.
Zn(CN) 2 is easy to make by combining aqueous solutions of cyanide and zinc ions, for example via the double replacement reaction between KCN and ZnSO 4: [5] ZnSO 4 + 2 KCN → Zn(CN) 2 + K 2 SO 4. For commercial applications, some effort is made to avoid halide impurities by using acetate salts of zinc: [5] [6] Zn(CH 3 COO) 2 + HCN → Zn(CN ...
The replacement image is still using the "equals" sign and the use of the down-arrow to indicate precipitation clearly indicates that the illustrated idea is the change--the reaction going forward--not a simple equivalence. My other quibble is that it is not quite clear what item has each given charge--would be clearer if color-coding were used ...

The reaction product is a greyish to white precipitate. This is the same synthesis from Berthelot in which he first found silver acetylide in 1866. [4] The double salt is formed in acidic or neutral silver nitrate solutions. Performing the synthesis in basic ammonia solution does not allow the double salt to form, producing pure silver ...
