When the reaction H3PO4 aq )+ Ca OH 2 AQ → H 3 PO 4 aq CA OH 2 AQ → occurs What is the formula for the salt formed Express your answer as a chemical formula?
Explanation: In this reaction, phosphoric acid, H3PO4, a weak acid, will react with calcium hydroxide, Ca ( OH ) 2, a strong base, to produce calcium phosphate, Ca3 ( PO4 ) 2, an insoluble salt, and water.
What happens when aqueous solutions of calcium hydroxide is combined with phosphoric acid?
An aqueous phosphoric acid solution reacts with an aqueous calcium hydroxide solution to produce water and solid calcium phosphate.
How do you balance chemical equations?
In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.
Is Ca3 PO4 2 soluble in water?
Calcium phosphate is insoluble in water but soluble in acids: it is used in natural farming. Calcium phosphate may dissolve slightly in CO2-containing water.
What is the formula of phosphoric acid?
Is H3PO4 a strong acid?
Strong acids are 100% ionized in solution. Weak acids are only slightly ionized. Phosphoric acid is stronger than acetic acid and so is ionized to a greater extent. Strong and Weak Acids and Acid Ionization Constant.
|HNO3 (nitric acid )||NO−3 (nitrate ion)|
|H3PO4 ( phosphoric acid )||H2PO−4 (dihydrogen phosphate ion)|
|CH3COOH (acetic acid )||CH3COO− (acetate ion)|

Is calcium hydroxide a strong base?
Some strong bases like calcium hydroxide aren’t very soluble in water. That doesn’t matter – what does dissolve is still 100% ionised into calcium ions and hydroxide ions. Calcium hydroxide still counts as a strong base because of that 100% ionisation.
How do you balance equations examples?
Examples of Balancing Chemical Equations Example 1. C5H12 + O2 —> CO2 + H2O. Example 2. Zn + HCl —> ZnCl2 + H2 Example 3. Ca(OH)2 + H3PO4 —> Ca3(PO4)2 + H2O. Example 4. FeCl3 + NH4OH —> Fe(OH)3 + NH4Cl. Example 5. S8 + F2 —> SF6 Example 6. C2H6 + O2 —> CO2 + H2O. Example 7. Al2(CO3)3 + H3PO4 —> AlPO4 + CO2 + H2O.
How do you balance equations with charges?
Balance charge. Add e– (electrons) to one side of each half-reaction to balance charge. You may need to multiply the electrons by the two half-reactions to get the charge to balance out. It’s fine to change coefficients as long as you change them on both sides of the equation.
Is Cus soluble in water?
Cuprous sulfide is insoluble in water but soluble in ammonium …
Is NI OH 2 soluble or insoluble?
Slightly soluble in water and denser than water.
