Hydrochloric acid is a kind of nutrient element and the basic metabolism of the human body, which is the foundation for maintaining normal metabolism. To check the nutrient elements and electrolyte solutions of the body, it is necessary to go to a professional internal medicine department to make a definitive diagnosis, and select the method of drug maintenance according to different conditions. Today, let’s interpret the reaction between hydrochloric acid and sodium oxide and see what kind of reaction will occur when these chemical molecules combine together?

Laboratory commonly uses edible salt and sulfuric acid to produce HCl gas

NaCl + H2SO4 = NaHSO4 + HCl (standard: heated) or 2NaCl + H2SO4 = Na2SO4 + 2HCl (standard: strong heat)

Hydrochloric acid can be obtained by dissolving HCl gas in water.

Since the 1960s, overseas pcb board hole metallization processes have used a colloidal solution of palladium activation process that combines sensitization and activation processes. In the early 1970s, some research institutes in China began to carry out research and development, and then it was applied and promoted in production. This colloidal solution of palladium activation solution is mainly used with concentrated hydrochloric acid and Sn2 as thickening agents, generally known as hydrochloric acid-collidal solution of palladium activation solution or high acid base type colloidal solution of palladium. Its advantage is to improve the bonding between the original copper base material and the organic plating layer. It changes the precious metal palladium catalytic layer replaced on the base steel plate after sensitization and activation treatment, thereby improving the bonding between the copper layer of the base material and the organic plating layer. Although this activating solution has achieved satisfactory results in production, it still has the following defects:

The colloidal solution of palladium based on acid requires a lot of hydrochloric acid during the configuration process, which is a harsh operating environment, and there are ecological environmental protection issues. The reliability of the colloidal solution of palladium is due to the presence of many Cl-. With the evaporation of hydrochloric acid, the Cl- in the solution decreases, and Sn2 oxidation in acidic and alkaline substances is faster, which affects the reliability of the colloidal solution of palladium water solution.

During the whole process of hole metallization, due to the exposure of the edge of the hole, the concentrated hydrochloric acid has a certain corrosive effect on the epoxy resin at the edge of the hole. This leads to a decrease in the bonding of the base material. The colloidal solution of palladium activated with salt has no such defects and is easier to configure than the hydrochloric acid-collidal solution of palladium activation. In addition, the amount of palladium used is also moderately reduced, at least it can achieve 1/10 of the palladium content in the acid-based palladium activation solution, while the specificity does not decrease. This type of activating solution, with NaCl as a thickening agent, can be called sodium oxide-collidal solution of palladium or low acid base collidal solution of palladium.

The advantage of the activating solution depends on: low hydrochloric acid content. Hydrochloric acid in the activating solution is just to dissolve Pd2, unlike in the hydrochloric acid-collidal solution where hydrochloric acid acts as one of the thickening agents, its hydrochloric acid content is only one-tenth of that of the high acid base collidal solution of palladium. It saves raw materials and reduces air pollution. The activating solution maintains this new type of collidal solution of palladium water solution for a long time with many Cl- from NaCl, which is different from the organic chemistry dipping activating solution of hydrochloric acid-pcb circuit board and organic chemistry dipping activating solution-pcb technical.

The metabolism of intestinal juice is habitual. Generally, it is believed that the chyme has a certain stimulating effect on the mechanical equipment of the mucosa. The function of hydrochloric acid is not clearly stated in the colon, in short, I have not seen such a term. The digestion and absorption in the intestinal phase can cause the metabolism of gastric acid, which is a neuro-humoral regulation.
