Answer:
Copper is a reddish-brown metal that is easily stretched to make wires. These characteristics are examples of Dhybral (physical/chemical) properties of copper.
Explanation:
When copper metal is heated in concentrated nitric acid, the copper dissolves to form a deep blue solution, and a brown gas is released from the acid.
If it takes 35.04ml of a 0.2455M NaOH solution to neutralize 25. 00ml of an unknown HCl solution, the molarity of the HCl solution is 0.34M.
<h3>How to calculate molarity?</h3>
The molarity of a solution can be calculated using the following formula:
C1V1 = C2V2
Where;
- C1 = molarity of acid
- C2 = molarity of base
- V1 = volume of acid
- V2 = volume of base
According to this question, it takes 35. 04ml of a 0. 2455M NaOH solution to neutralize 25.00ml of an unknown HCl solution. The molarity of the HCl can be calculated as follows:
35.04 × 0.2455 = 25.0 × V2
8.602 = 25C2
C2 = 8.6/25
C2 = 0.34M
As a result, the molarity of the HCl solution is 0.34M if it takes 35. 04ml of a 0.2455M NaOH solution to neutralize 25ml of an unknown HCl solution.
