The indicator will turn green when the right amounts of acid and alkali have been combined to make a solution of salt and water. This indicates that the solution has reached a neutral pH level.
It is unlikely for traces of marijuana to get into your system from just being around someone who is wearing clothing that has been in contact with the substance. However, if you are in an enclosed space with heavy marijuana smoke, it is possible for trace amounts to be inhaled and detected on a drug test.
One way to neutralize acid is by adding a base, which will react with the acid to form water and a salt. This reaction will decrease the acidity of the solution by balancing the concentrations of hydrogen ions and hydroxide ions. Additionally, using a pH indicator can help determine when the acid has been fully neutralized.
When the water of hydration has been removed, the substance is called an anhydrous compound. This means that the compound no longer contains water in its chemical structure.
Marijuana traces can be evident in urine upto a week after it was 'consumed'. The tests will only be able to work out when it was smoked insofar as a weaker sample would suggest it had some time to work it's way out of the system, but could simply suggest less was smoked or the subject has higher metabolism rate. Traces will be evident in blood samples for much longer, sometimes up to three weeks.
False
Traces of human life has been found on every corner of the globe. Including in the poles.
A fused alkali refers to a mixture of alkali metal salts that have been melted or fused together to form a homogeneous compound. This process helps to increase the solubility and reactivity of the alkali metals. These fused alkalis are often used in analytical chemistry and industrial applications.
