What happens when an acid is mixed with base?
When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.
What happens when an acidic solution is mixed with a basic solution?
Ans: When an acidic solution is mixed with basic solution then salt and water is formed . acid neutralizes the base and forms salt and water .
What color does litmus paper turn in acid?
red
What happened to solution BA and BB after mixing?
Answer. On mixing A and B , the solution becomes warm. This means heat released in formation of new bonds between A and B molecules is more than the heat absorbed for the breaking of molecules of A and B .
When a weak acid reacts with a strong base to form salt?
A salt that is derived from the reaction of a strong acid with a strong base forms a solution that has a pH of 7. An example is sodium chloride, formed from the neutralization of HCl by NaOH….Salts That Form Neutral Solutions.
| Salt formed from: | Salt Solution |
|---|---|
| Weak acid + Strong base | Basic |
What determines a weak acid?
A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. At the same concentration, weak acids have a higher pH value than strong acids.
Does diluting a weak acid change the pH?
Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When an acidic solution is diluted with water the concentration of H + ions decreases and the pH of the solution increases towards 7.
How do you find the pH of a weak base?
The procedure for calculating the pH of a solution of a weak base is similar to that of the weak acid in the sample problem. However, the variable x will represent the concentration of the hydroxide ion. The pH is found by taking the negative logarithm to get the pOH, followed by subtracting from 14 to get the pH.
Is acetic acid a base or acid?
Because of this release of the proton (H+), acetic acid has acidic character. Acetic acid is a weak monoprotic acid. In aqueous solution, it has a pKa value of 4.76. Its conjugate base is acetate (CH3COO−).
