It depends on the concentrations of these substances. However, sodium hydroxide is a very strong base and therefore is capable of producing solutions with high pH values. On the other hand, sodium hydrogen carbonate is weakly acidic, and is therefore capable of producing solutions that are somewhat less than neutral. (Carbonic acid is itself a weak acid.)

What is used as a food preservative-a.sodium benzoate b.sodium thiosulphate c.sodium hydroxide d.sodium bi carbonate?
Sodium benzoate is a preservative, e.g. in beveages, salads, pickles and seafood. It prevents spoilage by yeast at lower pH values (soured products).The other three are not.And only 'sodium bi carbonate' (sodium hydrogen carbonate is a better name) is used as auxillary in baking, called 'baking powder'.
Can I lower the pH of sodium hydroxide with water?
No, adding water to sodium hydroxide will not lower the pH. Sodium hydroxide is a strong base, and when dissolved in water, it dissociates to produce hydroxide ions, which make the solution more basic. To lower the pH of a sodium hydroxide solution, you would need to add an acid to neutralize the base.
How does the solubility of sodium carbonate in water change with varying temperatures?
The solubility of sodium carbonate in water increases as the temperature rises. This means that more sodium carbonate can dissolve in water at higher temperatures compared to lower temperatures.
Why is hydrogen collected at cathode instead of sodium during the electrolysis of sodium chloride?
When an aqueous solution of sodium hydroxide is electrolyzed, hydrogen is produced at the cathode because hydrogen can be produced at a lower voltage than can sodium, and the supply of hydrogen from the water of the solution is sufficient to consume all the current supplied. When molten sodium chloride is electrolyzed, however, sodium is produced at the cathode.
Why does sodium hydroxide have a pH then vinegar?
If you mean greater than the pH of vinegar, then the answer is sodium hydroxide is a base, which means it will have a pH greater than 7, and vinegar is an acid, which means it will have a pH less than 7.

What do you add to sodium hydroxide to get pH lower?
Acid
How does the solubility of sodium carbonate in water change with varying temperatures?

Does sodium rise or lower pH levels?
Sodium added to water react and form sodium hydroxide which is a strong base.

How does sodium carbonate affect the surface tension of water?
sodium carbonate has quite amount of salt in it. And the salt water is inversely proportional to water containing soap.Hence sodium carbonate affect the surface tension of water rather we say sodium carbonate loss the strength of the surface tension of the water.thanks by,(Arjun Babhulkar)
Why does sodium hydroxide have a pH then vinegar?
If you mean greater than the pH of vinegar, then the answer is sodium hydroxide is a base, which means it will have a pH greater than 7, and vinegar is an acid, which means it will have a pH less than 7.
Why does sodium carbonate not decompose when heated using?
Sodium carbonate does decompose when heated, but it requires a high temperature of around 851°C. At this temperature, sodium carbonate decomposes to form sodium oxide and carbon dioxide gas. Lower temperatures may not provide enough energy for the chemical reaction to occur visibly.
What is dilute sodium hydroxide?
Dilute sodium hydroxide refers to a solution containing a lower concentration of sodium hydroxide in water. It is commonly used in various industries for its alkaline properties, such as in cleaning agents or as a chemical reagent in laboratories. Dilute sodium hydroxide is less concentrated than its solid or more concentrated liquid forms, making it safer for certain applications.
Sodium reacts with water more vigorously than potassium. why?
Sodium reacts more vigorously with water than potassium because sodium has a lower ionization energy and is more reactive. When sodium comes into contact with water, it forms sodium hydroxide and releases hydrogen gas, resulting in a more rapid and vigorous reaction compared to potassium.
Why is carbon dioxide more soluble in sodium hydroxide than water?
Carbon dioxide is more soluble in sodium hydroxide than water because sodium hydroxide is a stronger base and can react with carbon dioxide to form a soluble compound (sodium bicarbonate). In contrast, water can only dissolve carbon dioxide through weak physical interactions like hydrogen bonding, which results in lower solubility.
