How to clean washing machine with vinegar and baking soda?
To clean with sodium carbonate (E500i, washing soda), run an empty hot cycle with about 1/2–1 cup to degrease and soften scale, then wipe seals and run a rinse. If you also use vinegar, do it in a separate cycle—acid and alkali neutralize each other if mixed.
Can you put baking soda in washing machine?
If you mean sodium carbonate (E500i, washing soda), yes—add a small amount with detergent to boost cleaning and soften water, but it’s more alkaline than baking soda. Avoid on wool/silk and follow fabric and appliance instructions.
How to make washing soda?
Convert baking soda to sodium carbonate (washing soda, E500i) by heating it on a tray at about 200°C/400°F for 30–60 minutes, stirring until it turns dull and grainy. Let it cool and store airtight, as it’s hygroscopic.
Can i put baking soda in washing machine?
If you’re thinking of washing soda (sodium carbonate, E500i), yes—use sparingly as a laundry booster; it’s stronger than baking soda. Always follow garment care labels and avoid on protein fibers like wool and silk.
Is baking soda good for washing fruits and vegetables?
A mild baking soda (sodium bicarbonate, E500ii) solution can help remove dirt and some residues; rinse well. Sodium carbonate (E500i, washing soda) is more alkaline and not recommended for produce washing.
Is monosodium phosphate bad for you?
At permitted food levels E339(i) is generally considered safe; EFSA has set a group ADI for phosphates of 40 mg/kg body weight per day (as phosphorus). Very high intakes may be a concern for people with kidney disease or those needing to limit sodium/phosphate.
Explain why an aqueous solution of monosodium phosphate would be ineffective?
As a buffer near neutral pH, a solution of only monosodium phosphate (NaH2PO4) is too acidic and lacks its conjugate base; effective phosphate buffering requires a mixture of mono- and disodium phosphate (H2PO4−/HPO42−) at the target pH.
How does monosodium phosphate make gas?
In leavening systems it acts as an acid that reacts with baking soda (sodium bicarbonate) to release carbon dioxide gas, which aerates doughs and batters; by itself it does not generate gas.
How to change the ph of protein solution without precipitation using monobasic sodium phosphate?
Use a phosphate buffer pair: slowly titrate with small amounts of monobasic (NaH2PO4) and disodium phosphate (Na2HPO4) to reach the target pH, staying away from the protein’s isoelectric point and keeping the buffer modest (e.g., ~10–50 mM). Make adjustments gradually with constant stirring and temperature, maintaining ionic strength (a little NaCl can help) to minimize precipitation.
How to clean up monosodium phosphate?
For small spills, avoid dust, sweep or scoop up the solid and rinse the area with water; for solutions, absorb with inert material and dispose according to local regulations. Because it’s highly water‑soluble and nutrient-rich, avoid flushing large amounts to drains or waterways.
