A soil sample has an Exchangeable sodium percentage (ESP) of 16%, its electrical conductivity is 3.2 Milli-Mohs/cm and a pH of 9.5. How is the soil classified?

A soil sample has an Exchangeable sodium percentage (ESP) of 16%, its electrical conductivity is 3.2 Milli-Mohs/cm and a pH of 9.5. How is the soil classified? Correct Answer Alkaline soil

The three classes of salty soil are based on these three properties pH range, ESP, and conductivity of saturated extract. Alkali soil has pH range in between 8.5 and 10, ESP greater than 15, and conductivity of saturated extract less than 4 milli-mhos/cm at 25°C.

Measurement of KLa in a bioreactor can be carried out by sodium sulfite oxidation method, that is, based on the oxidation of sodium sulfite to sodium sulfate in the presence of a catalyst (Cu++ or Co++). In a typical experiment, a laboratory fermenter was filled with 5 liter of 0.5 M sodium sulfite solution containing 0.003 M Cu++ ions and the air was sparged in. After 10 min, the air flow was stopped and a 10 mL sample was taken and titrated. The concentration of sodium sulfite in the sample was found to be 0.20 M. The oxygen uptake rate for this aerated system will work out to be

A teacher is trying to introduce her class VII students to different kinds of soil. She begins by introducing the names of three kinds of soil i.e. sandy soils, clayey soil and loamy soil. She explains the properties of each soil in term of its particulate nature. She then demonstrates one sample of each kind of soil and shows the students the difference in percolation rate of an examples. How would you evaluate this approach from an inquiry oriented perspective?

A researcher conduct a hypothesis test and observes values from sample mean and sample standard deviation when n = 25, that do not lead to rejection of null hypothesis. He calculates the p value as 0.0667. What will happen to the p value if he observes the same sample mean and standard deviation for a sample > 25?
