Answer:
CuO + H₂SO₄ ⟶ CuSO₄ + H₂O
Explanation:
The most likely reaction is a <em>double displacement</em>, in which Cu and H trade partners.
This gives
CuO + H₂SO₄ ⟶ CuSO₄ + H₂O
The equation is already balanced, so no further work is necessary.
The solution that conducts electricity and has a pH value of 7 would most likely be a neutral solution. Water is among the best examples of a neutral solution. When the pH of a solution is considered to be lesser than 7, it is an acid, while if the pH is greater than 7, it is considered to be a basic solution.
A strong acid- strong base titration is performed using a phenolphthalein indicator. Phenolphtalein is chosen because it changes color in a pH range between 8.3 – 10. It will appear pink in basic solutions and clear in acidic solutions. ... It is known as the titrant.
Concave is not a type of mechanical wave because it doesn’t need a medium for propagation.
