What else can I help you with?
What word describes the solution formed by an acid or alkali?
The word is "salt." When an acid reacts with a base (alkali), a neutralization reaction occurs, forming a salt and water.
What do you observe when you dip blue litmus paper into solution with pH lees than 7?
Blue litmus paper will remain blue or possibly turn slightly red in a solution with a pH less than 7, indicating that the solution is acidic. This change occurs because blue litmus paper only changes color to red in acidic solutions.
You place a drop of a solution on red lemons paper no color change occurs what can you conclude?
You can conclude that the solution is not acidic in nature since red litmus paper does not change color in the presence of an acidic solution. Further testing with a different indicator may be needed to determine the nature of the solution.
What happens when acidic solution react with alkaline solution and how?
When an acidic solution reacts with an alkaline solution, a neutralization reaction occurs. The hydrogen ions (H+) from the acid and hydroxide ions (OH-) from the base combine to form water (H2O). The resulting solution is neutral, with a pH of 7.
Why does phenol red change yellow?
Phenol red changes yellow in acidic conditions due to a shift in its chemical structure, which occurs when the hydrogen ions in the solution cause the indicator to undergo a color change. This change is reversible when the solution becomes basic again.
When a base is mixed with acidic solution neutralization occurs because?
when a base is mixed with an acidic solution why does neutralization occurs?
If a reaction occurs when a piece of metal is placed in a solution what can you conclude about the solution?
It is acidic because bases rarely react with metals.

What words describe the reaction of an acid and a alkali?
Neutralization reaction occurs when an acid and an alkali react, resulting in the formation of water and a salt. This reaction typically involves the transfer of protons from the acid to the alkali, leading to the formation of a neutral solution.
When alkali is added to aced it is neutralized?
When alkali is added to acid, a neutralization reaction occurs where the hydrogen ions from the acid react with the hydroxide ions from the alkali to form water and a salt. This process results in the solution becoming neutral in terms of pH.
What color change the occur when phenolphthalein is put into the base?
Phenolphthalein changes from colorless to pink in a basic solution. This color change occurs because phenolphthalein is a pH indicator that is clear in acidic solutions and pink in basic solutions with a pH above 8.2.
What liquid solution becomes red in an acid?
Phenolphthalein solution turns red in an acidic environment. This color change occurs due to the shift in the pH of the solution, which causes phenolphthalein to undergo a chemical transformation and display a red hue in acidic conditions.
What happens when you add an alkali to an alkali?
A chemical reaction. Acid + alkali = salt + water eg H2SO4 + 2NaOH = Na2SO4 + 2H2O Sulfuric acid + Sodium Hydroxide = Sodium Sulfate + water Whan as acid meets an alkali they create a chemical reaction. If there is an acid and you add a weak alkali you should bring it down to neutral.
