15 حقائق عن HCl + ZnCO3: ماذا وكيف توازن والأسئلة الشائعة


HCl + ZnCO3 is one of the reactions of HCl with weak bases like ZnCO3. Let us see how the reaction works.

ZnCO3 is a smithsonite mineral that occurs in nature as a white solid. Its melting point is 140°C, and it has less solubility. HCl, a strong acid, can completely dissociate into the aqueous solutions. Its melting point depends upon the concentration of the solution.

In this article, we will go through some of the facts of this reaction, like its products, intermolecular forces, and displacement reaction type.

What is the product of HCl and ZnCO3

HCl reacts with ZnCO3 to form zinc chloride, water, and carbon dioxide gas.

2HCl(عبد القدير) + ZnCO3 (ق)= ZnCl2 (عبد القدير) + CO2(ز) + ح2O(L)

What type of reaction is HCl + ZnCO3

HCl + ZnCO3 reaction can be considered an تفاعل الحمض القاعدي since HCl, a strong acid, reacts with weak base ZnCO3 لتشكيل الملح والماء.

  • Therefore, the balanced chemical equation for the above reaction is given by:

2HCl(عبد القدير) + ZnCO3 (ق)= ZnCl2 (عبد القدير) + CO2(ز) + ح2O(L)

HCl + ZnCO3 المعايرة بالتحليل الكيماوي

The below data gives an idea about the titration of HCl versus ZnCO3.

جهاز

Conical flask, measuring jar, volumetric flask, wash bottle, pipette, burette, burette stand, watch glass.

مؤشر

Since it is a strong acid versus weak base reaction, the phenolphthalein indicator is used; its endpoint is pink to colorless.

إجراء

Burette is filled with standardized HCl, and ZnCO3 is taken into a conical flask and start titration by dropwise addition of HCl and add indicator in the middle and titrated until the solution becomes colorless. It is the equivalent point; note down the readings, find the volume of ZnCl2 using the formula V1S1=V2S2.
