2. What properties do all acids have?

1 answer:

3 0

2. They taste sour, are electrolytes, and react with active metals to produce hydrogen.

3. You should NEVER taste unknown chemicals because many are poisonous and can destroy body tissue.

4. Most often dyes are used to detect acids. The dyes will turn a certain color which indicates the presence of an acid.

10. You can use litmus to detect wether a solution is a base or an acid.

11. The most common bases I can think of would be: baking soda, laundry detergent, or soaps.

12. Antacids work by neutralizing the acids in your stomach.

13. When an acid and base are mixed together, they produce a salt.

14. Normally pH meters are used, but you can also calculate the pH using math. (yuck)

15. The pH scale measures how acidic or basic a substance is. It ranges from 0-14, with 7 being neutral.

17. pH is very important to the environment as it helps us measure and monitor for safe water conditions. A rise or fall from the average water pH level can indicate chemical pollution.

18. Salt is formed when an acid and base react with each other. It then has a cation of the base, and anion of the acid.

I hope those helps!! (:

A chemist titrates 150.0 mL of a 0.2653 M carbonic acid (H2CO3) solution with 0.2196 M NaOH solution at 25 °C. Calculate the pH

xxTIMURxx [149]

Answer:

9.3

Explanation:

This is long and complicated so get ready

We are going to use the conjugate base of carbonic acid with water to make carbonic acid and OH- (Na is simply a spectator ion and is irrelavent here)

Let the conjugate base be A- and Carbonic acid be HA

A- + H20 ⇄ HA + OH-

To find the concentration of A- we must find the concentration of the reactants given. We know this will be equal because it is a strong base and all of it disassociates.

to get moles of acid we take the concentration and multiply by liters to cancel

.2653 x .150 = .039795 mol HA

Because it is at equivalence point we know the moles will be equal. We are given the concentration so we only have to solve for liters

We plug it into the equation and found: .181 L

Now use moles and combined volums to fins concentrarion which is .120 M

Now plug that use the Ka converted to Kb to find the cincentrations of HA and OH-

Ka is (10^-3.60) = 2.4E-4

Kb x Ka is 10^-14

Kb = 3.98E-11

Now we know Kb = [HA] [OH] / [A-]

Solve for this through algebra by using x for the values you dont know

youll find x^2 = 3.3E-10

X = 1.8 E -5

this is the OH- concentration

-log [oh] = pOH

pOH = 4.73

We know 14-pOH = ph so pH= 9.3

Battery acid has a density of 1.285 g/mL and contains 38.0% sulfuric acid by mass. The car battery contains 1.45 L of battery ac

larisa86 [58]

Answer: 708.2 grams

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Given : 38 g of $H_2SO_4$ is dissolved in 100 g of solution.

Density of solution = 1.285 g/ml

Volume of solution = $\frac{mass}{density}=\frac{100g}{1.285g/ml}=77.8ml$

Thus if 77.8 ml of $H_2SO_4$ contains = 38 g of $H_2SO_4$

1.45L= 1450 ml of $H_2SO_4$ contains = $\frac{38}{77.8}\times 1450=708.2 g$ of $H_2SO_4$

Therefore, the mass of the sulfuric acid in a car battery is 708.2 g

Can someone please explain this i will give brainliest

IrinaVladis [17]

1) 2
2) 2
3) there are 2 atoms of hydrogen and 1 atom of oxygen, altogether is 3
4) subscript tells how many atoms of each element are present in the molecule
5) No, it is not balanced because the oxygen atom is not equal on both sides of the reactants and products. This wouldn’t be considered balanced as there are two oxygen atoms in the reactants section and only one oxygen on the products section.

It is:
2 H2 + O2 -> 2 H2O

9 different lab rules Explain how students will do a safe lab

motikmotik

Answer:

Report all accidents, injuries and breakage of class or equipment to instructor immediately.
Keep pathways clear by placing extra items on the shelves or under the work tables. If under the tables make sure that these items can no be stepped on.
Long hair (chin-length or longer) must be tied back to avoid catching fire.
Wear sensible clothing including footwear. Loose clothing should be secure so they do not get caught in a flame or chemicals.
Work quietly - know what you are doing by reading the assigned experiment before you start to work. Pay close attention to any cautions described in the laboratory exercises.
Do not taste or smell chemicals.
Wear safety goggles to protect your eyes when heating substances, dissecting, etc
Do not attempt to change the position of glass tubing in a stopper.
Never point a test tube being heated at another student or yourself. Never look into a test tube while you are heating it.

Hope this helps:))
