Summary Introduction
Introduction:
The pH is the measure of the concentration of hydrogen ions in a solution. If the concentration of H+ ions increases in a solution, the solution is said to be acidic with a pH of less than 7 and a lower concentration of H+ ions means the solution is alkaline with a pH of more than 7.
The carbonate pathway is the body’s mechanism to keep the pH balanced. The organs in the body can only function at a definite pH. Changing the pH of the body by consuming acidic or alkaline substances or by a synthesis of different compounds in the body can harm us if the pH is not restored back to normal. This is done by buffer systems in the body.

Suppose you have a solution of 0.1 M H2CO3 and 0.1 M NaHCO3.
Which of the following reactions takes place with addition of small
amount of NAOH to this buffer solution?
O H* + HCO3¯ -->H2CO3
O OH + HCO3 --> H2O + C0,2-
O none of the choices
O OH + H*
--> H2O
Please balance the following half-based reactions:
SbH3 → Sb (acidic solution)
BrO3- → Br2 (acidic solution)
Cl- → ClO2- (basic solution)
(PLEASE DONT USE H+ ION INSTEAD SUB H30+ )
Suggest an appropriate reason for the observation : “On increasing temperature of the reacting system by 10 degrees, the rate of reaction almost doubles or even some times becomes five folds.”

- Reactants: Sodium Hydroxide (NaOH) Potassium Permanganate (KMnO4) Glucose (C12H22O11) What is the purpose of the sodium hydroxide in the redox reaction experiment?arrow_forwardWhich of the following correctly explains why the vapor pressure of water has to be included in the calculations? Some of the liquid water evaporates into the gas, and increases the total pressure generated by the trapped gas. As the H2(g) is bubbled up the reaction solution, some of the H2(g) molecules are solubilized by water in the aqueous solution, effectively decreasing the measured pressure above. The pressure contributed by the H2(g) is greater than the measured total pressure because of the contribution of partial pressure of water vapor. The pressure exerted by the evolved H2(g) is reduced because of the co-presence of water vapor, thus Pwater vapor has to be added to Pdry gas.
