Calculate the mass of solid ammonium chloride required to mix with 100 ml of 1.0m ammonia to prepare a 9.25 ph buffer

Chemistry
1 answer:
Lyrx [107]3 years ago
4 0
Given: 

Volume of base = 100 mL
Concentration of base = 1.0 m
pkb of ammonia = 4.75
ph of buffer = 9.25

pOH = pkb + log [salt]/[base]
         = 4.75 + log[salt]/[1.0m]
calculate for the pOH. 

pH = 14 - pOH

If a gun is found in water, what should investigators do to transport it to the lab?
GREYUIT [131]
<span>Most items of evidence will be collected in paper containers such as packets, envelopes, and bags. Liquid items can be transported in non-breakable, leakproof containers. Arson evidence is usually collected in air-tight, clean metal cans. Only large quantities of dry powder should be collected and stored in plastic bags. Moist or wet evidence (blood, plants, etc.) from a crime scene can be collected in plastic containers at the scene and transported back to an evidence receiving area if the storage time in plastic is two hours or less and this is done to prevent contamination of other evidence. Once in a secure location, wet evidence, whether packaged in plastic or paper, must be removed and allowed to completely air dry. That evidence can then be repackaged in a new, dry paper container. UNDER NO CIRCUMSTANCES SHOULD EVIDENCE CONTAINING MOISTURE BE PACKAGED IN PLASTIC OR PAPER CONTAINERS FOR MORE THAN TWO HOURS. Moisture allows the growth of microorganisms which can destroy or alter evidence.
