Which of the following statements is wrong? ! a. in volumetric analysis, the volume of standard solution required to react completely with analyte is measured b. a standard solution is the one of very well-known concentration of a substance c. a primary standard material must be hygroscopic, and of high purity d. at equivalence point of acid-base titration, the indicator changes color e. solid naoh is not a suitable primary standard

did anyone actually do this? like if anyone has submitted this i rly need .

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
