What happens to rubidium chloride when added to water?
Rubidium is a large sized atom of alkali metals family and is highly reactive towards water when it is added in water Rubidium hydroxide is formed along with bubbles of hydrogen gas this hydroxide is strong alkali so pH value of water shows a change from 7 to 12 , 13 or 14.
Describe a solution that contains a buffer?
Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
What do indicators test for?
Indicators are used to test if something for example whether vinegar is an acid or alkali. Due to the pH scale, 1 - 3 is a strong acid, 4 - 6 is a weak acid, 7 is neutral, 8 - 10 is a weak alkali and 11 - 14 is a strong alkali. Vinegar should turn orange when added with an indicator, with the pH of about 3.
Describe the differences between the behavior of the buffer solution and the pure water upon the addition of alkali?
A buffer solution will resist changes in pH when an alkali is added, as it contains a weak acid and its conjugate base which can neutralize the alkali. Pure water will undergo a significant increase in pH upon addition of an alkali as there are no other components present to buffer or resist the pH change.
What color would phenoplhthalein turn if drano was added?
Phenolphthalein would turn pink when added to Drano, which is a strong alkaline substance. This color change indicates that the solution has become basic.
What alkali could be added to a strong acid to neutralise it?
To neutralise a strong acid, you would need a strong alkali (or lots of a weak alkali, but that would be impractical). Potassium hydroxide, sodium hydroxide, lithium hydroxide, calcium hydroxide, calcium hydroxide and magnesium hydroxide would all work.
How can you describe the way the pH changes when a strong acid is added slowly to a strong alkali?
As a strong acid is added slowly to a strong alkali, the pH will gradually decrease due to the neutralization reaction. Initially, the pH will increase as the alkali is added, then start to decrease as the acid is added until it reaches a neutral pH of 7 when the acid and alkali are fully neutralized.
What is acid neutral?
alkalis / bases neutralise acids, a method in which to do this is titration where the acid is slowly added to the alkali through a burette until the mixture is neutral
Will the pH change when an alkali is added to an acid?
Yes, the pH will change when an alkali is added to an acid. The addition of an alkali to an acid will result in the neutralization reaction, forming water and salt. This reaction will change the pH towards being more neutral.
What element forms an alkali when added to water?
Potassium is an element that forms an alkali solution when added to water. It reacts vigorously with water to produce potassium hydroxide, which is a strong base.
What changes in PH occurs if an alkali is slowly added to an acidic solution?
The actual answer depends on the strength of the acid / alkali used. However the pH will change from around 1-6 to 8-14 depending on the strength of the acid / base. pH ~1 for strong acid pH ~6 for weak acid pH ~8 for strong base pH ~14 for strong base

Why is lime added to acidic lakes?
Lime is a strong base. When you add a base to an acid it turns it neutral. So by adding the lime to the water after a while it'll turn into precipitation itself and neutralize the acid. This is also known as acid-base neutralization.
Why is there a temperature changes when alkali is added to vinegar?
When an alkali (base) is added to vinegar, the acetic acid in the vinegar reacts with the alkali. These reactions are nearly all exothermic, that is, they generate heat as the chemical reaction proceeds. This is observed by a change in the temperature of the aqueous solution and the surrounding air.
If red litmus is added to a alkali?
When red litmus is added to an alkali, its colour changes to blue. This is because an alkali is a base and has the property of turning red litmus paper or red litmus solution to blue.
What solution would alkali and acid give if added together?
It would depend on which acid and alkali were involved, the general rule is that adding an acid to an alkali will produce a salt and water. Sulphuric acid and sodium hydroxide would give sodium sulphate + water Hydrochloric acid and potassium carbonate would give potassium chloride and water and carbon dioxide etc
