Answer:
Na⁺ and HCO⁻₃
Explanation:
When baking soda is dissolve in water it fully ionized into positive and negative ions.
NaHCO₃ + H₂O → Na⁺ + HCO⁻₃
The Na⁺ than react with OH⁻ of water and produced NaOH while HCO⁻₃ react with H⁺ and produce H₂CO₃. This carbonic acid than break to produced carbon dioxide and water.
H₂CO₃ → H₂O + CO₂
Properties of baking soda:
It is odorless compound.
It is solid at room temperature.
It is used in medicine to cure the acidity of stomach.
It is used to make baking powder.
The concentration of hydrogen ions in a solution is a measure of its acidity. So the correct option is (b) false.
When an Arrhenius acid is dissolved in water, hydrogen ions are produced:
H+(aq) + A- = HA + H2O (aq)
Here, H+ is the hydrogen cation, A- is the solvated anion, also known as the conjugate base, and HA is the non-dissociated acid. When an Arrhenius base is dissolved in water, hydroxide ions are produced:
BOH + H2O → B+(aq) + OH-(aq)
Is a material with at least one hydrogen atom that has the ability to split apart in an aqueous solution to produce an anion and an H + ion (a proton), creating an acidic solution. Bases are substances that, when dissolved in water, create hydroxide ions (OH) and a cation, resulting in a basic solution.
