Universal indicator is a solution that changes what in an acidic or alkali solution?
Universal indicator doesn't change anything in an acidic or alkali solution. All universal indicator does is show how acidic or alkaline a solution is (red being acidic, green being neutral and blue being alkali)
Which ion is excess in alkali solution?
OH- ions are present in excess in alkaline solution
How does a hydronium ion differ from a hydroxide ion?
Hydronium ion is 'H^(+) The Hydroxide ion is 'OH^(-)'. #1. One is positively charged , the other is negatively chsrged. #2 ; one does not contain oxygen atom, the othe does. #3 ; in solution they combine to form water.
What is the product neutralization of acid and alkali?
The product of neutralizing an acid and alkali is water and a salt. The acid donates a hydrogen ion (H+) while the alkali donates a hydroxide ion (OH-), forming water (H2O). The remaining ions combine to form a salt, which is a compound composed of a metal ion from the alkali and an anion from the acid.
Is ammonia a strong alkali?
Yes, ammonia is a weak alkali. It is a weak base that can accept a proton to form the ammonium ion.
What is the charge on an alkali metal ion?
the charge on all alkali metal ions is 1 +
How do you know if an ionic compound between an alkali metal with a nonmetal is done correctly?
Since all alkali metals form a 1+ ion, the number of alkali metal atoms in the formula should be equal to the charge on the negative ion.
Universal indicator is a solution that changes what in an acidic or alkali solution?
Universal indicator doesn't change anything in an acidic or alkali solution. All universal indicator does is show how acidic or alkaline a solution is (red being acidic, green being neutral and blue being alkali)
Which ion is present in all acid solutions?
Hydrogen
What reaction causes aqueous solutions of alkali metal carbonates to be basic?
Aqueous solutions of alkali metal carbonates are basic because they undergo hydrolysis in water, producing hydroxide ions that increase the pH of the solution. The carbonate ion reacts with water to form a hydroxide ion and bicarbonate ion, effectively raising the concentration of hydroxide ions in the solution and making it basic.
Which ion is excess in alkali solution?
OH- ions are present in excess in alkaline solution
What is the ion present in all basic solutions?
The hydroxide ion, OH-, is present in all basic solutions. It is responsible for the characteristic properties of basic solutions, such as a bitter taste, slippery feel, and ability to turn litmus paper blue.
What ion is produced when any alkali is dissolved in water?
This is the hydroxyl ion OH-.
How do you distinguish an acid from an alkali?
an acid donates the h plus ion and alkali does the opposite
What is the alkali metal with two electrons in its plus 1 ion?
This alkali metal is lithium (Li).
What ion charges do the alkali metals form?
Alkali metals forn cations with the chrage +1.
How does a hydronium ion differ from a hydroxide ion?
