Buffer action refers to the ability of a buffer solution to resist changes in its pH when small amounts of acid or base are added. Le Chatelier's principle states that when a system at equilibrium is subjected to a stress, it will respond by shifting in the direction that helps to relieve that stress. In the case of a buffer solution, adding small amounts of acid or base can be considered a stress. The buffer solution will respond by shifting its equilibrium so as to consume the added acid or base, thereby maintaining a relatively stable pH.
Adding NaOH will increase the pH of water, because NaOH is a base. At 25°C: pH < 7 is an acidic solution pH = 7 is a neutral solution pH > 7 is a basic solution
This reaction is:NaCl + H2SO4 = NaHSO4 + HCl
The reaction is:2 H2O2-----------------2 H2O + O2
The reaction is:2 H2O2-----------------2 H2O + O2
NaHCO3 + HNO3 = CO2 + H2O + NaNO3
Na2CO3 + CaCl2 >> CaCO3 + 2 NaCl ( double replacement)
Mg + 2HCl = MgCl2 + H2 SO magnesium chloride and Hydrogen gas

Sodium "disappears" when it reacts with water because the reaction converts sodium atoms to monovalent sodium cations, which remain in solution in the water as part of the compound sodium hydroxide. As with all other solutions, this one is homogeneous and therefore does not show the presence of solute, but a mass balance would show that the total mass is the same as the sum of masses of the sodium and water reacted, minus of the mass of the hydrogen gas that is formed by reaction and escapes from the solution into the atmosphere.
CdS(s)+H2SO4(aq)--> Cd2SO4(aq)+H2S(g) one of the byproducts of this reaction will be gas Hydrogen Sulfide, H2S
the chemical equation for the decomposition of calcium hydrogen carbonate is given below.Ca(HCO3)2(aq) → CO2(g) + H2O(l) + CaCO3(s).It is a balance chmeical reaction.

Ethanoic acid is another name for acetic acid, which has the chemical formula CH3COOH. The reaction in solution is CH3COOH produces CH3CO2- + H+.
