- A sample is known to consists of NaOH, or NaHCO3 or Na2CO3 or possible compatible mixture of these, together with inert matter. With methyl orange, a 1.100 g sample requires 31.4 ml of HCl ( 1.000ml is equivalent to 0.0140 g CaO). With phenolphthalein , the same weight of the sample requires 13.3 ml of the acid. Calculate the percent inert matter in the sample? ( ans. 17.7%)A sample is known to consists of NaOH, or NaHCO3 or Na2CO3 or possible compatible mixture of these, together with inert matter.

- Will heating beef tallow in the presence of acid instead of base produce soap?Explain.(a) In 20 or less of yourown words define the term “leachate”and describe how it forms. (b) Previous records had shown that to prevent acute toxicity to organisms, the maximum mass of CdSO4 that should be allowed into the landfill was determined to be 0.1 kg. This was calculated using a standard concentration of Cd in mg/L where the volume of the leachate pond was used as 500 000L. (i) Provide the name of the CdSO4 compound. State the oxidation number of Cd in this compound (ii) You need to ensure that the concentration used to determine the mass of Cd allowed in the landfill, meets the current regulatory standard. Assuming that previous calculations determined that all of the CdSO4 would be deposited in the leachate pond, what standard concentration of Cd in mg/L was used to determine the maximum mass of allowable CdSO4?Explain what type of carbonate polymorphs may be present in saw dust derived biochar prepared at 300 degrees?
