Can sodium and calcium form salt?
No. Sodium and calcium, both being metals, will not combine chemically. Table salt is a compound of sodium and chlorine.
Would it matter if droplets of distilled water were left in the buret when it was filled with sodium?
Yes, as it will serve to dilute the concentration of the sodium hydroxide being placed in the buret. You will being adding a known concentration of sodium hydroxide and ending up with an unknown concentration.

What happens when you add zinc to sodium chloride?
When zinc is added to sodium chloride, a displacement reaction occurs where the zinc replaces the sodium in the compound. This results in the formation of zinc chloride and sodium being left separate.
Why is the atomic mass of sodium 22.990 and not 22?
The atomic mass of sodium is 22.990 because it is an average mass of all naturally occurring isotopes of sodium, taking into account their relative abundances. Sodium has multiple isotopes with slightly different masses, which contributes to the atomic mass being a non-integer value.
Why is sodium thiosulfate being put in microbiological water containers?
Sodium thiosulphate neutralises chlorine, so preventing further bactericidal effects on organisms in the water during transit to the laboratory. (ie. results of analysis will be representative of sample at time of sampling.)
Equation between potassium iodate and sodium thiosulphate?
The equation between potassium iodate (KIO3) and sodium thiosulfate (Na2S2O3) involves a redox reaction. In the presence of an acid, potassium iodate is reduced to iodine (I2), while sodium thiosulfate is oxidized to form sodium tetrathionate (Na2S4O6). The balanced chemical equation for this reaction is 5Na2S2O3 + 2KIO3 + 8HCl → 5Na2S4O6 + 2I2 + 2KCl + 6H2O.
What type of chemical reaction when sodium thiosulphate is dissolving in water?
When sodium thiosulfate dissolves in water, it undergoes a physical change rather than a chemical reaction. The sodium thiosulfate molecules are surrounded by water molecules, causing them to separate and disperse throughout the solution. This process is known as dissolution, where the ionic compound breaks apart into its constituent ions without any chemical bonds being broken or formed.
What are the benefits of using organic powdered whole milk compared to regular powdered milk?
Organic powdered whole milk offers benefits such as being free from synthetic chemicals and pesticides, higher nutritional content due to minimal processing, and better taste and quality compared to regular powdered milk.
Does bromine react with soduim?
Yes: Bromine reacts with sodium to form sodium bromide.
What color does the indicaror turn when mixed with powdered juice?
The answer will depend on which indicator is being used.
Definition of antal?
Not quite sure if you meant: Anteal: meaning being before, or in front. or Intal: meaning it's used for a preparation of cromolyn sodium
What substance is being oxidized when sodium reacts with chlorine gas?
In this reaction, sodium is being oxidized. When sodium reacts with chlorine gas, sodium atoms lose electrons to form sodium ions, and this process involves the loss of electrons, which is characteristic of oxidation.
What happens when sodium peroxide comes in contact with sodium thiosulfate?
An exothermic reaction will occur, with the peroxide being reduced and the thiosulfate being oxidized.
How should one properly dispose of a sodium hydroxide solution?
To properly dispose of a sodium hydroxide solution, it should be neutralized with an acid, such as vinegar, before being poured down the drain with plenty of water. It is important to wear protective gear and follow safety guidelines when handling and disposing of sodium hydroxide.
Can sodium and calcium form salt?
No. Sodium and calcium, both being metals, will not combine chemically. Table salt is a compound of sodium and chlorine.
Why is baby's buttocks red?
Baby isn't being changed, washed, oiled and powdered often enough.
