L-Serine is an amino acid that often is provided when intravenous feeding solutions are used to maintain the health of a patient. Molecular weight of 105, produced by fermentation and recovered and purified by crystallization at 10C. Yield is enhanced by adding methanol to the system, thereby reducing serine solubility in aqueous solutions. An aqueous serine solution containing 30wt% serine and 70wt% water is added along with methanol to a batch crystallizer thatis allowed to equilibrate at 10C. The resulting crystals are recovered by filtration; liquid passing through the filter is known as filtrate, and the recovered crystals may be assumed in this problem to be free of adhering filtrate. The crystals contain a mole of water for every mole of serine. The crystal mass recovered in a particular laboratory runis 500g, the filtrate is determined to be 2.4wt% serine, 48.8% water, and 48.8% methanol a.) draw and label a flowchart for the operation and carry out a degree of freedom analysis. Determine the ratio of mass of methanol added per unit mass of feed b.) laboratory process is to be scaled to produce 750 kg/h of product crystals. Determine required feed rates of aqueous serine solution and methanol

The amino acid glycine is often used as a component of buffers in biochemical experiments. The amino group of glycine has a pKa of 9.6, which can exist in the protonated form -NH3+ or the free base -NH2 as shown in this equilibrium: R-NH3+ ⇌ R-NH2 + H+ (a) Using glycine as a buffering agent requires specific pH ranges. Identify the buffer range for glycine’s amine group and describe how this molecule provides buffer capabilities as small amounts...

Intravenous, or IV solutions used in medicine must exert the same osmotic pressure as blood to prevent a net flow of water into or out of the blood cells. The proper concentration for an intravenous NaCl solution is 0.90 g NaCl per 100. mL of water (sometimes refered to as 0.90% m/v). If the van\'t Hoff factor of NaCl is i = 1.8, what is the osmotic pressure of blood at body temperature, 37 °C?
