When preparing dilute solutions of an acid, carefully pour - a. both liquids at once b. the acid into the container c. the acid into the water d. water into the acid?

When preparing dilute solutions of acid, carefully pour the acid into the water.

Explanation:

Acid is a chemical substance that gives hydronium ions in their aqueous solution.

Their aqueous solution tastes sour.They are used to neutralize the alkali solution. Like hydrochloric acid neutralizes sodium hydroxide to give sodium chloride and water as a product.The acid solution with a larger amount of acid in its solution is considered a concentrated acid solution.The acid solution with a smaller amount of acid in its solution is considered a dilute acid solution.The concentrated acid solution can be changed into a dilute acid solution by adding the concentrated acid solution in water slowly and with constant stirring.Do not add water in concentrated acid solution as water and acid reacts vigorously which can cause water to boil and acid to splash.

So, from this, we conclude that when preparing dilute solutions of acid, carefully pour the acid into the water.

Explanation:

If there is no heat to transfer from one bottle to the other, then both bottles are at an equilibrium. This just means that they're both on the same thermal energy level.
