To clean acidic crystals, a 1% to 2% sodium bicarbonate aqueous solution can usually be used. The concentration of sodium bicarbonate can also be adjusted according to the specific situation of the acidic crystals. For example, highly acidic crystals may require a more concentrated sodium bicarbonate solution.
Specifically:
Generally acidic crystals: 1% to 2% sodium bicarbonate aqueous solution is a more commonly used concentration, which can effectively neutralize the acidity and avoid damaging the crystals.
Highly acidic crystals: The concentration of sodium bicarbonate can be appropriately increased, such as 3% or 4% solution.
Special cases: If the crystals are also sensitive to weak alkaline solutions, consider using a lower sodium bicarbonate concentration, or use other weak alkaline solutions.
Other precautions:
Solubility:
Sodium bicarbonate has limited solubility in water. Generally speaking, a concentration of 1% to 2% is already relatively easy to dissolve.
Operation:
When cleaning, you can first immerse the crystals in a sodium bicarbonate aqueous solution, and then gently wipe them with a soft brush or cotton cloth.
Rinse:
After washing, you need to rinse with pure water to remove the residual sodium bicarbonate solution.
In general, it is a common and safe practice to use 1% to 2% sodium bicarbonate aqueous solution to clean acid crystals. If you encounter special circumstances, you need to adjust the concentration according to the specific situation.
