What else can I help you with?
Is it true that The pH scale measures the concentration of hydroxide ions?
No, pH measures the concentration of hydrogen ions. pOH would measure hydroxide concentration.
A base is a substance that forms hydroxide ions in a water solution.?
A substance that forms hydroxide ions in a water solutoin is a base -- TRUE -- apex:)
A n is a substance that either contains hydroxide ions OH- or reacts with water to form hydroxide ions?
Bronsted-Lowry's BASES are a substance that either contains hydroxide ions OH- or reacts with water to form hydroxide ions.
What is the number of Hydrogen ions in 5.18 g of strontium hydroxide?
Strontium hydroxide is Sr(OH)2, with a molar mass of 121.6g/mol. If you have 5.18g of it, you have 5.18/121.6=0.0426mol of it. Multiply this by Avogadro's number to get 2.56x1022 representative particles of strontium hydroxide. Assuming you mean hydroxide ions instead of hydrogen ions, it's 2 hydroxide ions per formula unit, so double it to get 5.12x1022 hydroxide ions.
What type of ions do base produce in water?
Hydroxide ions (OH-)
Is an acid a substance that produces hydroxide ions in a water solution?
False
A substance that forms hydroxide ions in a water solution is a base?
Yes, that is correct. Bases are substances that release hydroxide ions (OH-) when dissolved in water, leading to an increase in the concentration of hydroxide ions in the solution. Examples of bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
Is it true that The pH scale measures the concentration of hydroxide ions?
No, pH measures the concentration of hydrogen ions. pOH would measure hydroxide concentration.
A base is a substance that forms hydroxide ions in a water solution.?
A substance that forms hydroxide ions in a water solutoin is a base -- TRUE -- apex:)
Which of the following is true about bases they tend to decrease PH solution or they release hydroxide ions in solutions?
Technically, neither is entirely true. Bases will not decrease the pH, but neither do they always release hydroxide. For example, ammonia and the amines are basic, but this is because they remove hydronium, not because they add hydroxide. They release hydroxide ions in solution.
What is true about the relative concentrations of hydronium and hydroxide ions in an acid solution?
In an acidic solution, the relative concentration of hydronium ions will always be higher than hydroxide ions. This means that the relatively concentration of hydroxide ions will always be lower than hydronium ions in an acidic solution. The reason for this is that in a neutral solution, the concentration of both hydronium ions and hydroxides ions are equal (both are 10-7). By making the concentration of hydronium ions greater than the concentration of hydroxide ions, the solution becomes acidic.
What ions form when sodium hydroxide dissolves in water?
When sodium hydroxide (NaOH) dissolves in water, it forms sodium ions (Na+) and hydroxide ions (OH-). The sodium ions are positively charged and the hydroxide ions are negatively charged.
Do acids produce hydroxide ions?
No, actually they produce hydrosonium ions in an aqueous medium.
What substance that releases hydroxide ions into water?
A substance that releases hydroxide ions into water is a base. Examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH). When these substances dissolve in water, they dissociate into ions, including hydroxide ions (OH-), which result in an alkaline solution.
How many ions does potassium hydroxide have?
Potassium hydroxide is an ionic lattice. It has two types of ions and namely they are potassium ions and hydroxyl ions.
When a base forms hydroxide ions there is an increase in concentration of what ion?
Hydroxide Ions
A base forms which ions in solution?
hydroxide ions are formed by bases and hydronium ions are formed by acids.
