Dissolution of any material is faster in powdered form.
No. Sodium and calcium, both being metals, will not combine chemically. Table salt is a compound of sodium and chlorine.
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.

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.
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.
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.)
This reaction may be misunderstood as a direct reaction between the thiosulphate and iodate ions , however, in practice an iodide and acid mediated production of iodine from the iodate is used to react with the thiosulphate. A standard reaction used to calibrate a solution of sodium thiosulphate is as follows: Acid and potassium iodide are added to a solution of potassium iodate getting the following reaction: KIO3 + 5KI + 3H2SO4 = 3I2 + 3K2SO4 + 3H2O represented by the following ionic equation: IO3- + 5I- + 6H+ = 3I2 + 3H2O Thiosulpathe is titrated against this solution (effectively against iodine): I2 + 2Na2S2O3 = Na2S4O6 + 2NaI represented by the following ionic equation: I2 + 2S2O32- = S4O62- + 2I- where the dark brown coloured solution of iodine turns pale yellow and finally colourless as the reaction proceeds (starch is used as indicator after the pale yellow transition forming a black solution due to an iodine-starch complex which turns colourless upon further addition of thiosulphate).
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.
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.
Yes: Bromine reacts with sodium to form sodium bromide.
The answer will depend on which indicator is being used.
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
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.
An exothermic reaction will occur, with the peroxide being reduced and the thiosulfate being oxidized.
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.
Baby isn't being changed, washed, oiled and powdered often enough.
The herb is available powdered or as a tincture. The dosage varies according to the condition being treated.
