ABSTRACT Heats of neutralization of sulphuric and hydrochloric acids by sodium hydroxide have been determined‚ using a microcalorimeter of the Tian-Calvet type. The range of concentrations employed was 5x10-" N to 3x10-* N‚which is sufficiently low to permit an accurate extrapolation to be

inflammation usually results from a gallstone blocking the flow of bile. • Typically‚ people have abdominal pain that lasts more than 6 hours‚ fever‚ and nausea. • Ultrasonography can usually detect signs of gallbladder inflammation. • The gallbladder is removed‚ often using a laparoscope. Cholecystitis is the most common problem resulting from gallbladder stones. It occurs when a stone blocks the cystic duct‚ which carries bile from the gallbladder Causes In 90% of cases‚ acute cholecystitis

With reference to acid-base balance explore the role of the respiratory system in maintaining blood pH? ‘We live and die at the cellular level’ (Reid‚ 2011). Homeostasis is crucial for normal cellular function. Acid-base homeostasis is the part of human homeostasis and refers to the balance between the production and elimination of H+ hydrogen ions (pH) within the body fluids (William‚ Simpkins‚ 2001‚ p.236).

the concentration of the acid solution changes the rate of the reaction between dilute hydrochloric acid and magnesium metal. • As the metal reacts with the acid‚ hydrogen gas is produced and the metal dissolves. To get an estimate of the rate of reaction‚ the time taken for a small piece of magnesium ribbon to dissolve (disappear) can be measured. This is a “clock reaction” and the reaction rate is proportional to 1/time taken SAFETY Dilute hydrochloric acid is harmful. Wear safety spectacles
