A freshly prepared sodium hydroxide (NaOH) solution is standardized against number one
fashionable potassium acid phthalate (KHC8H4O4). 0.8000 grams of potassium acid phthalate
became dissolved into 50 mL CO2-unfastened water. 2-three drops of phenolphthalein had
been added. The pattern became titrated to a faint purple endpoint with 22 mLs sodium
hydroxide. What is the normality of the sodium hydroxide? - ANS-zero.178 N
A plant serving a metropolis of 50,000 population has an influent settleable solids of 10 mL/L. If
according to capita contribution to the plant flow is one hundred gallons/day, how a great deal
sludge is produced inside the plant in cubic feet/day? - ANS-6,684 cu toes/day
A preliminary test designed to set up approximate toxicity of a solution is called a: - ANS-variety
finding take a look at.
A test wherein solution is changed constantly in take a look at chambers thru the check length is
referred to as a: - ANS-glide via take a look at.
A check in which solutions and take a look at organisms are positioned in take a look at
chambers and stored there for the duration of the test is known as a: - ANS-static take a look at.
A toxicity test designed to set up concentration at which a specific stop point takes place is
known as a: - ANS-definitive take a look at.
A waste is considered risky if it has as a minimum one of the following properties: -
ANS-ignitability, corrosivity, reactivity, and toxicity.
, Alkalinity - Bottle, Preservation, Hold Time - ANS-250mL plastic/glass, unpres, 14 days
Ammonia - Bottle, Preservation, Hold Time - ANS-500ml plastic/glass, pH<2 H2SO4, 28 days
Basic requirements for toxicity assessments do now not consist of: - ANS-documented re-use of
control test organisms.
