Is HCl (Hydrochloric acid) an Acid or Base? Answer: HCl (Hydrochloric acid) is an acid. Explanation: Today we will know about whether HCl (hydrochloric acid) is an acid or Base in just four steps.               Step-1: HCl gives hydrogen ion into water ,H₂O.We know that an acid gives hydrogen ion  in water.So  HCl  is an acid. HCl  is an acid according to  Arrhenius  concept of acid and base concept. HCl  ----> Cl  + H +                          Step-2: HCl  reacts with an base to produce salt and water.So  HCl  is an acid. HCl  +NaOH ----> NaCl  + H₂O HCl =Acid NaOH =Base NaCl=Salt H₂O =Water               Step-3: HCl  gives proton(H + ) to a base NH₃.Since  HCl  is a proton donar ,  HCl  is an acid.According to Brønsted–Lowry  concept of acid and base , also called  proton theory of acids and bases ,  HCl  is an acid. HCl  +NH₃ ---->  NH₄Cl                          Step-4 : HCl  turns blue  litmus paper into  red .We know that an acid can do that.So, HCl  is an a

Is KOH(Potassium hydroxide) an Acid or Base ? Answer: Yes,KOH is a base. Explanation: Today we will know about whether KOH(Potassium hydroxide) is an acid or base in just three steps.               Step-1: KOH gives hydroxide ion into water ,H₂O.We know that an base gives hydroxide ion  in water.So KOH is an base. KOH(aq.) ----> K +  (aq) +  OH -  (aq.)                          Step-2: KOH reacts with an acid H₂SO₄ to produce salt and water.So KOH is an base. H₂SO₄ (Acid) +KOH (Base) ----> K₂SO₄ (Salt)  + H₂O H₂SO₄ =Acid KOH =Base K₂SO₄=sodium sulphate H₂O =Water                                         Step-3 : KOH turns red  litmus paper into blue .We know that an base can do that.So,KOH is  an base. continue

Is NH3 (Ammonia) an Acid or Base? Answer: NH3 (Ammonia) is a base. Explanation: Today we will know about whether NH₃(ammonia) is an acid or base in this blog post.               Step-1: NH₃ gives a pair of electrons to  H +  or another species or a molecule and thus  NH₃  forms a covalent bond. NH₃ can donate a pair of electrons because in the lewis structure of  NH₃,  we get one lone pair of electrons over N atom(: NH₃). We know that an base gives a pair of electrons  to another ion or molecule according to lewis theory of acid and base.So,  NH₃  is an base. 2H₃ N: +Ag  ⁺  ---->    [Ag(NH₃)₂]⁺. Here two molecules of  NH₃   have donate two pair of electrons to  Ag  ⁺.That is why  NH₃   is an lewis base and  Ag  ⁺   is a lewis acid.                          Step-2: NH₃  reacts with an acid HCl to produce NH⁺₄Cl⁻ .Here  NH₃ is a proton acceptor and HCl is proton donar.  According to  Bronsted-Lowry concept,an base is a substance which  has the tendency to accept a proton .On the other

Is NaOH(Sodium hydroxide) an Acid or Base ? Today we will know about whether NaOH(Sodium hydroxide) is an acid or Base in just three steps.               Step-1: NaOH gives hydroxide ion into water ,H₂O.We know that an base gives hydroxide ion  in water.So NaOH is an base. NaOH(aq.) ----> Na +  (aq) +  OH -  (aq.)                          Step-2: NaOH reacts with an acid H₂SO₄ to produce salt and water.SoNaOH is an base. H₂SO₄ (Acid) +NaOH (Base) ----> Na₂SO₄ (Salt)  + H₂O H₂SO₄ =Acid NaOH =Base Na₂SO₄=sodium sulphate H₂O =Water                                         Step-3 : NaOH turns red  litmus paper into blue .We know that an base can do that.So,NaOH is  an base. continue

Is H2SO4(Sulphuric acid) an Acid or Base ? Today we will know about whether H2SO4(Sulfuric acid) is an acid or Base in just four steps.               Step-1: H₂SO₄  gives hydrogen ion into water ,H₂O.We know that an acid gives hydrogen ion  in water.So H₂SO₄ is an acid. H₂SO₄ is an acid according to  Arrhenius  concept of acid and base. H₂SO₄ ----> SO₄²-  + H +                          Step-2: H₂SO₄ reacts with an base to produce salt and water.So H₂SO₄ is an acid. H₂SO₄ +NaOH ----> Na₂SO₄  + H ₂O H₂SO₄ =Acid NaOH =Base Na₂SO₄=sodium sulphate H ₂O =Water               Step-3: H₂SO₄ gives proton(H + ) to a base NH₃.Since H₂SO₄ is a proton donar , H₂SO₄ is an acid.According to Brønsted–Lowry concept of acid and base , also called  proton theory of acids and bases , H₂SO₄ is an acid. H₂SO₄ +NH₃ ----> (NH₄)₂SO₄  + H ₂O                          Step-4 : H₂SO₄ turns blue   litmus paper into red .We know that an acid can do that.So, H₂SO₄ is an acid. continue

  What is a prime number? Answer: A prime number is that number that has only two divisors or factors.The first divisor or factor is 1 and the second divisor or factor is itself. ●A prime number is that number that is the product of 1 and itself. ●A prime number has the following characteristics: 1.It is greater than 1 2.It has only two factors. 3.It can't be negative number.It is always positive number. Now let us take some examples. ●2 is an example of a prime number because it has only two divisors.The first divisor is 1 and the second divisor is 2 (itself) 2 =1×2 The number 2 is a prime number because it is the product of 1 and itself. ●3 is an example of a prime number because it has only two divisors.The first divisor is 1 and the second divisor is 3 (itself) 3 =1× 3 The number 3 is a prime number because it is the product of 1 and itself. ●5 is an example of a prime number because it has only two divisors.The first divisor is 1 and the second divisor is 5 (itself)
