What happens when HCl is added to a buffer solution?
When HCl is added to a buffer solution, it reacts with the components of the buffer to form a new equilibrium. The buffer's ability to resist changes in pH is reduced, but it still maintains some buffering capacity. The pH of the solution may decrease slightly depending on the amount of HCl added.
What happens if aluminum is added in dilute hcl?
When aluminum is added to dilute hydrochloric acid (HCl), a chemical reaction occurs. The aluminum reacts with the HCl to form aluminum chloride and hydrogen gas. The reaction is exothermic and produces bubbles of hydrogen gas as it proceeds.
Why do casein precipitate only at pH 4.6?
it is because casein has an isolectric point at 4.6, milk has a pH of 6.6. Casein at this pH has a negative charge, when added with an acid, the phosphate group found in casein is protonated, and when the pH reaches to 4.6, then the casein would then be aggregated, becoming insouluble to milk
What is the terms for the lumps that form when an acid is added to milk?
The term for the lumps that form when acid is added to milk is curdling. This happens when the casein in the milk reacts to the acidity.
What do you observe when dilute HCl is added to Na2CO3 in a test tube?
When dilute HCl is added to Na2CO3 in a test tube, effervescence (bubbling) occurs due to the formation of carbon dioxide gas. This is because the reaction between the acid and carbonate produces carbonic acid, which quickly decomposes to release CO2 gas.
What happens to the equilibrium when hcl is dissolved in water?
When Dilute HCL is added to water a more diluted solution of HCl is made.
What happens when hcl is added to a fertilizer?
This depends on the type of fertilizer; phosphates for ex. can react.

What does hydrochloric acid do to casein and gelatin?
Hydrochloric acid (HCl) denatures proteins like casein and gelatin by disrupting their structural integrity. This process unfolds the protein molecules, leading to a loss of their original shape and function. In the case of casein, HCl can cause precipitation, leading to curd formation in dairy products. For gelatin, the acid can break down the protein structure, affecting its gelling properties.
Why add CaCO3 in isolation of casein?
Calcium carbonate is added to neutralize the excess of acetic acid which remain after the precipitation of casein.
Why curd is added to warm milk?
because of a bacteria called casein
Why do casein precipitate only at pH 4.6?
it is because casein has an isolectric point at 4.6, milk has a pH of 6.6. Casein at this pH has a negative charge, when added with an acid, the phosphate group found in casein is protonated, and when the pH reaches to 4.6, then the casein would then be aggregated, becoming insouluble to milk
What happens when HCl is added to NaCl?
the concentration of Cl- increase (common ion), but the pH of the solution remain same.
What happens when HCL is added to solution with a pH of 7.45?
When hydrochloric acid (HCl) is added to a solution with a pH of 7.45, the acidity of the solution increases. HCl dissociates into hydrogen ions (H⁺) and chloride ions (Cl⁻), which lowers the pH as the concentration of hydrogen ions rises. The solution will become more acidic, moving toward a pH closer to neutral (7) or even below, depending on the amount of HCl added. This change can affect various chemical equilibria and biological processes that are sensitive to pH.
What are other names for casein?
αS1 casein αS2 casein β-casein κ-casein
What new substance is formed if vinegar is added to milk?
The product of this chemical reaction is casein, a protein.
