4) a) It is a good habit to start by inspecting the reaction by writing the balanced equation : 2 NaOH + H2SO4 ‐‐> 2H2O + Na2SO4; This is a titration problem.

A reaction between sulfuric acid and sodium hydroxide is of an acid-base type, or is also known as a neutralization reaction. In this process, both compounds undergo a reaction to neutralize the acid and base properties. The products of this process are salt and water.

Na2SO4

NaOH + H2So4 gives Na2So4 + H2O – Chemistry Q&A.

Sodium acetate (CH3COONa) is a solid-state salt that can not be used in anhydrous or liquid form as an acid or base. Now, with NaOH being a strong base and CH3COOH being a weak acid, the resulting solution is fundamental in nature.

For example, the acetate ion is the conjugate base of acetic acid, a weak acid. Therefore, a soluble acetate salt, such as sodium acetate will release acetate ions into the solution, which a few of these will interact with water, forming unionized acetic acid and the hydroxide ion.

Tripotassium phosphate is a strong base.

Since HNO2 (aq) is only a weak acid, NO2 – will act as a weak base. Therefore, the solution of NaNO2 will be basic. ➋ ➊ Example 1b. Find the pH of a 0.10 mol/L solution of NaNO2 (aq).

We’re asked to determine in an aqueous solution of LiNO2 is acidic, basic or neutral. Recall the definition of a Brønsted-Lowry Acid and a Brønsted-Lowry Base. Therefore, it is a proton acceptor and based on the definition, aqueous LiNO2 is a Brønsted-Lowry base. Aqueous LiNO2 is basic.

Lithium carbonate is somewhat toxic. It is a base, and reacts with strong acids.

Potassium carbonate (K2CO3) is a very weakly acidic compound (based on its pKa).
