- Normal arterial pH is 7.35 to 7. 45. Both metabolic and respiratory alkalosis have pH more basic compare to the normal arterial pH. The difference is 0.5 units. What is pH value in alkalosis? Niemann-Pick type C disease is a progressive neurological disease; symptoms include unsteady walking with uncoordinated limb movements, slurred speech, a difficulty in swallowing, epilepsy and tremor. This condition is due to the abnormal functioning of a lysosome. State the normal functions performed by this organelle.Define the following:- pH- Buffer- pKaThe pHpH scale for acidity is defined by pH=−log10[H+] where [H+]is the concentration of hydrogen ions measured in moles per liter (M). A solution has a pH of 10.2. Calculate the concentration of hydrogen ions in moles per liter (M).
- Fill the following table by choosing the correct answers. Treated by Possible Caused by pH value metabolic acidosis metabolic 수 alkalosisCalcium carbonate (CaCO₃(s)) is an important building material (limestone) and a quick cure for acid indigestion (TUMS). Ksp = 8.7x10⁻⁹ for CaCO₃(s). What, if any, is the effect of lowering the pH (as occurs in acid rain and acid indigestion) on the solubility of CaCO₃(s). (hint: use Le Chatelier's principle) A) there is no effect from lowering pH on CaCO₃(s) solubility B) lowering pH increases the CaCO₃(s) solubility C) additional information is required to determine the outcome D) lowering the pH lowers the solubilityThe normal pH of blood is 7.35-4.45. The normal pCO2 level is 35-45mmHg. John has blood work performed. His recorded pH is 7.1. His recorded PCO2 is 20mmHg. Based on this describe the acid base state of John. (ie, metabolic acidosis, metabolic alkalosis, respiratory acidosis, and respiratory alkalosis). Support your answer.
