(c) the color turns deep dark and then at certain level, it turns back to light green.
(d)fastest.
Answer:
unchanged
Explanation:
KHP is potassium hydrogen phthalate. It is a weak acid. It forms a colourless ionic weakly acidic solution which can be titrated against NaOH to determine the concentration of a sodium hydroxide solution. KHP is used as a primary standard. Its concentration depends on the mass of solid added and the volume of solution.
If all the KHP was not transferred into the flask, the experimental value of the concentration of NaOH remains unchanged as long as the titration was carried out correctly and following normal procedure. Only the concentration of the KHP will be affected by this error during calculation.
Answer is: A. covalent bonds.
Insulator most likely has covalent bonds, because it must have low electrical conductivity.
1) Substances with covalent bond not conduct an electric current in liquid and solid state, because they not have free ions or electrons.
2) Substances with ionic bond conduct an electric current in liquid, but not in solid state, because in liquids ions are mobile, contrary to solids where ions are fixed.
3) Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.
When we assume that there is a complete reaction, then the water is being absorbed by the soap formed because it has a hydrophilic nature or it can bind to water. Also, the amount of water is less than the amount of the soap formed that can dissolve the soap completely therefore we see a solid cake of soap.
I think its A). Carbon dioxide/iron
