Answer:
We will use an acid-base indicator to see changes in colour depending on the pH
Explanation:
The pH changes during a titration, so you could use an acid-base indicator to follow the changes in pH.
A is wrong. An acid-base titration does not usually form a solid, and it would be impractical to isolate a solid with a funnel.
B is wrong. There are no changes in mass.
C is wrong. Any changes in temperature would be too small to measure precisely with an ordinary thermometer.
Answer:
"hydrogen to oxygen"
Explanation:
Hydrogen bonds are formed when hydrogen is bonded to highly electronegative element such as Chlorine, fluorine, oxygen etc.
In hydrogen bonding, the hydrogen atom of one molecule of water is attracted to the oxygen atom of another molecule of water via permanent dipole-dipole interaction.
Hence, If you have 2 water molecules together, they always sit "hydrogen to oxygen" as a result of dipole - dipole interaction and hydrogen bonding between water molecules.
Answer:
}
the color of the pH balance is dark blue
Explanation:
A pH indicator corresponds to a substance that measures the pH of the solution in question. in the case of neutral substance the color that the solution takes is dark blue, if it is acidic it turns pink or red and basic of a green tone. Some examples of indicators: phenolphthalein, bromophenol blue, methyl red, among others.
Answer:
the atoms of the original substances gain, lose and even share their very own electrons. write the symbols of the elements that form the compound. Write down the valency, and lastly go over valencies. This is all I got so far. I hope this helps
