Question

50 ml of 0.1 M solution of sodium acetate and 50 ml of 0.01 M acetic acid are mixed. The pKa of acetic acid is 4.76. Then yh pH of this buffer solution is ​

Answer 1

Reaction of sodium with water. Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H2). ... The reaction is exothermic. During the reaction, the sodium metal may well become so hot that it catches fire and burns with a characteristic orange colour.

Answer 2

the ph of the buffer solution is 5.76
