Sep 19, 2018 · If you had more base than acid, there would be leftover base and the final solution would be basic (pH > 7). A similar outcome occurs when one or both of the reactants are 'weak'. A weak acid or weak base doesn't fully break apart (dissociate) in water, so there may be leftover reactants at the end of the reaction, influencing the pH.

Note:While mixing acid and water, in case any strong acid is mixed, then utmost care has to be taken in the order of pouring the acid and water. Always acid is added to water, and not water into an acid, as strong acids would result in the release of energy as the reaction will be highly exothermic.
Apr 26, 2018 · Acids and bases can combine in other ways, however, and when they do, the product isn't always a salt. For example, when you add zinc to ammonia, the reaction results in a complex ion. Until the introduction of the Lewis theory of acids and bases, this wouldn't even have been considered an acid/base reaction.
Jun 13, 2023 · In general, bases react with hydrogen ions. This is how neutralization happens. The acid produces hydrogen ions, and the base produces hydroxide ions. These react together to make water. The anion that came from the acid and the cation are left, so if you evaporate the water, you would get a salt. The general reaction looks like this:

There are a few factors that make it better to add acid to water. Diluting acid with water is exothermic, so it’s easier to boil and splash water added to acid than acid added to water because water has a high heat capacity and can absorb a lot of heat. Also, some strong acids have a higher specific gravity or densitythan water. So, if you put wate...
Sulfuric acid (H2SO4) is the most dangerous common acid to dilute. Partly, this is because it reacts so violently with skin and clothing. Sulfuric acid quickly dehydrates proteins and carbohydrates in skin and muscle. The acid is much heavier than water, so water added to it reacts with the top layer first. A lot of heat gets generated, even when s...
In general, the higher the concentration the acid, the greater the greater the heat increase and the higher the chance of boiling and splashing. Be extremely careful diluting any concentrated strong acid. Always wear proper safety gear and work under a fume hood. No matter what acid you’re diluting, remember reaction rates double for every 10 degre...
Here are some easy mnemonic devices to help you remember to add acid to water: 1. AA: Add Acid 2. Acid to Water, like A&W Root Beer 3. Drop acid, not water 4. If you think your life’s too placid, add the water to the acid 5. First the water, then the acid, otherwise it won’t be placid
Like strong acids, strong bases react with water in an exothermic reaction. Also, like the strong acids, strong bases tend to be corrosive and able to cause chemical and thermal burns on skin. It’s best to add base to water, just like you would acid.

Dover Publications.Sep 16, 2022 · The acid and base have neutralized each other, and the acidic and basic properties are no longer present. Salt solutions do not always have a pH of 7, however. Through a process known as hydrolysis, the ions produced when an acid and base combine may react with the water molecules to produce a solution that is slightly acidic or basic. As a ...

Set-up three clear cups or containers. Pour a mixture of water and vinegar (an acid) in one, water (neutral) in another and a mixture of water and Milk of Magnesia (a base) in the third. Add a tablespoon of cabbage juice to each container. You may need to add additional indicator to get a color change, depending on how much acid or base you have.
