Step-by-step explanation:
A student investigated the reaction of aqueous potassium hydroxide with two different
acids, acid C and D.
Two experiments were carried out.
Experiment 1
By using a measuring cylinder, 40 cm of aqueous potassium hydroxide was poured into a
conical flask and the initial temperature of the solution was measured.
A burette was filled with acid C up to the 0.0 cm mark.
10 cm of acid C was added to the potassium hydroxide in the flask. The temperature of the
mixture was measured?
Answer:
Limewater is the common name for a dilute aqueous solution of calcium hydroxide. Calcium hydroxide, Ca(OH)₂, is sparsely soluble at room temperature in water. "Pure" limewater is clear and colorless, with a slight earthy smell and an astringent/bitter taste. It is basic in nature with a pH of 12.4.
