So, is baking soda actually a strong base? [duplicate]
Based on my recent thoughts, when baking soda ($\ce{NaHCO3}$) is dissolved in water, the following hydrolysis reaction occurs:
$$\ce{NaHCO3 + H2O <=> NaOH + H2CO3}$$
However,
$$\ce{H2CO3 -> ...

Reversibility of an acid's reaction with water depending on its strength
This is how my chemistry professor compared reaction of a weak and a strong acid with water:
$$\ce{HCl + H2O -> H3O+ + Cl- + Heat}$$
In this case $\ce{H2O}$ breaks the bond between $\ce{H}$ ...

Molar concentration of water and pKa value
By defintion, $\mathrm pK_\mathrm a$ value is defined as
$$\mathrm pK_\mathrm a = -\lg ([\ce{H2O}] K_\mathrm{eq})$$
Consider the reaction:
$$\ce{HCl + H2O <=> H3O+ + Cl-}$$
The Eq constant of $...
